Nature 258, November 20 1975
This is a particularly worthy book, one which has long been needed by theoretician and experimentalist alike. Approximately the first half of the book leads one through a very detailed discussion of all aspects of the necessary theory, stressing the role of the perfect lattice, the electronic structure of the defect, and lattice dynamics. All the major theoretical models are discussed and their short comings made clear, in some cases brutally so. I think that the solid-state theorist will enjoy this part of the monograph particularly, although for the beginner it will be a daunting task. Many theorists will also find the second half of the book invaluable as the comparison of experiment and theory is especially well presented. Not only will it be informative, but it may imbue the reader with the motivation, so evident in all Stoneham’s work, to attempt calculations of direct applicability to experiments already done and still to be done. This last part of the book will be much used by the experimentalist, not simply “to know what, if anything, they should believe of the present theories’’ but also because it will give them a clearer vision of the interaction between theory and experiment in solid-state physics.

Review by Professor Brian Henderson



Physics Today,
March 1976

Solids are known for the cornucopia of defects of all degrees of pathological complexity that determine most of their properties; by now the number of defects must have surpassed even the plethora of elementary particles. All of these defects have structural as well as electronic aspects, although in many instances only one type is dominant. To treat all of them with any theoretical deail in one book would have been an unmanageable undertaking, and the resuit would have been much longer than A. M. Stoneham’s nearly 900 pages. Stoneham has therefore limited the scope of his book to defects in insulators and semiconductors, with only an incidental mention of metals and heavily doped semiconductors. He has also concentrated on the theoretical aspects of the electronic properties of these defects; in fact, nearly half of the book is concerned with theoretical methods, rather than theoretical results. The presentation and intercomparison of advantages and disadvantages of various theoretical approximations and schemes is very complete and detailed. One consequence is that, when it comes to experimental data, only those are given that are essential for guidance or comparison with theory. The stress is placed on directly observable electronic phenomena (such as optical transitions, photoionization, local modes, infrared absorption, external fields end resonance) of static defects. Hardly any mention is made of kinetic and dynamic questions of the formation, motion and annealing of defects, although the elec tronic aspects of these phenomena are often crucial, as illustrated by the frequent failure of the simple point or shell-model theories. The book is not and does not intend to be an encyclopedia of defects. Rather, it is a very systematically written survey of the variety of theoretical approaches necessary for the study of defects. The author’s attitude is well illustrated by the first sentence of his chapter on vacancies in valence crystals: “There is no adequate theory of the defects discussed in this chapter.” True but disconcerting.

Upon reading this book, one realizes why defects in insulators and semiconductors provide such a rich field for theory: even though usually many kinds of defects are simultaneously present, (1) they can often be observed individually, (2) they produce many easily measurable effects, either electronic or optical or elastic or resonance and (3) last but not least, they are not hidden behind the sometimes quite impenetrable curtain of electrons in metallically conducting solids. The author avoids dwelling too long in the many areas where he made his own major contributions (polarons, F, Vk and H-centers, quantum theory of diffusion and so on), and the result is a very uniform, coherent and pleasing presentation. The book also strikes a happy medium between being a text book and a monograph, with a thoroughness of presentation and explanation that makes it suitable for graduate students. The wide coverage. the list of nearly 2000 references and a fair subject index make it a true monograph on theoretical methodology in this particular field. In that sense it is unique and of great value to all interested in the basic aspects of defects in solids

Beauty of defects
Early concepts of solid state physics were developed on the model of a perfect crystal - an ideal which proved extreme fruitful in generating a whole new branch of science. While it was recognized from the outset that defects were an inevitable and often a highly beneficial ingredient in any real solid. For a tong lime it was considered sufficient to regard them as small perturbations of the perfect host lattice and, in any case, to treat them as isolated and non-interacting entities. Only gradually did the impact of developing technology - of, for example, heavily doped and later amorphous semiconductors, or the progressive refinement of semiconductor devices or superionic conductors - demand a better understanding of the fundamental processes involving defects. The interaction of defects, exemplified by the phrase “ecology of solid state pollution”, as a keyword-conscious researcher described simultaneous diffusion of two impurities in silicon, became increasingly a topic of detailed study. Haves and Stoneham’s book is an important and probably a unique addition to the literature of this subject. It is remark able in several respects. First, it combines outstanding readability with a depth of treatment which can be deceptive in that it can give the reader the impression that he has understood a certain point, until on closer examination he will find that on any single page there may be several other matters raised which require further study. The treatment is made both interesting and illuminating by the frequent inclusion of summary tables and other “integrating” features which bring together aspects of the subject not nor mally found under one heading, such as a full-page glossary of the main species of excitons. The second unusual feature is the inclusion of many theoretical discussions which start with the simplest concepts and bring in, sometimes almost as asides, progressive refinements of approach which demand much wider reading. If one wishes to delve further, the up-to-date bibliography is very helpful: if not, one has at least been left under no illusion that the simple picture is the end of the matter. The following chapter headings give an impression of the sheer breadth of the book’s contents: “Electronic Properties (mainly of perfect lattices but with electron-hole drops thrown in for good measure); “Interatomic Forces and Atomic Motions” (including defects and amorphous solids); “Lattice Defects” (with a discussion of fast ionic conduciors): Spectroscopy of Solids’ (with descriptions of optical, EPR and DLTS techniques): Electronic Properties of Point Defects (with a comprehensive review of defects in many different materials): Radiation-induced Defect Processes (ranging from radiation damage and ion implantation to laser annealing and photolysis; Properties of Surfaces (with special emphasis on defect phenomena and including a discussion of sintering) and finally Special Systems (which manages to include amorphous solids, metal-insulator transitions. intercalates and polymers).

The book will be a challenge to able final-year students - it will broaden their horizons but they should beware of becoming too engrossed in the detail - while for post-graduates this will be an ideal text to provide the background to many research topics. Teachers, too, will here find inspiration, though it may be necessary to dig deep into the subsidiary literature to follow up the items which are mentioned almost casually in the text. To a large degree. this is much more than a didactic text and has many features of a reference source. The seemingly effortless way in which the authors treat a wealth of topics should not deceive anyone into thinking that things are all that easy.

Comments Solid State Physics 12 97, 1986

Seldom do I come upon a book in which a great deal of information has been synthesized in a new, enjoyable, and helpful manner. With delight I have found this to be such a book. Focusing on the electronic and vibrational properties of defects in nonmetallic solids, it covers many areas in a descriptive rather than a mathematical manner. It is written for people who have a background in solid state physics, but in a style and depth that will make it a useful supplement to students who are taking a course in solid state phys ics or materials science. Also, many research workers would enjoy spending several evenings with the book; it will help them to put their work in a more general context by increasing their awareness of related areas. The first chapter provides background for the rest of the book with an outline of electron band theory and defect electron states as well as polarons and excitons. Then lattice dynamics is discussed for crystals containing point defects, mixed crystals, and amor phous solids. In the next chapter the thermodynamics of defect formation and diffusion, lattice relaxation and dimensional changes due to defects are discussed. Next optical effects are considered, including defect lattice vibration effects, and nonradiative transitions, with an introduction to the use of electron paramagnetic resonance (EPR) and deep level transient spectroscopy (DLTS). Then the electronic properties of some important examples, such as the V- (and related) centers, transition metal impurities, shallow donors and acceptors, and other important impurities in semiconductors are discussed. Radiation damage in alkali halides and semiconductors is focused on next. The following chapter describes surfaces including relaxation and reconstructions, vibration, electronic surface states, as well as oxidation, corrosion, and catalytic effects. In the last chapter amorphous solids are discussed, as well the metal-insulator transition, and intercalated compounds. The broad scope of the hook is apparent. Although the topics are not considered deeply, the book is well written and the cov erage is well done. I am sure that many scientists will find this a helpful and enjoyable book.

Contemporary Physics 27 372, 1986
This book is a welcome change - a text on the defect solid state with a difference. And the authors are to be warmly commended for that. Superficially the contents page does not suggest such a difference, for it is the freshness of its approach which sets this book apart from earlier texts. Dr. Hayes and Dr. Stoneham have well-earned reputations for their many major contributions to the physics of defects in non-metals, so that one might reasonably have anticipated an approach developed specifically from their earlier writings. This has been avoided, even though the authors have culled numerous well-chosen examples from their own researches. The book has an impressive breadth, achieved essentially by treating only the general features of the subject to the exclusion of detailed case histories. In consequence a vast array of topics and materials have been described. The first three chapters areconcerned with underlying theoretical concepts of band structure, defect electronic states, lattice dynamics and the thermodynamics of defect formation, all nicely illustrated with pertinent experimental data. Chapters 4 and 5 discuss the spectroscopic properties of defects (including impurities) and their interactions with lattice vibrations. Chapter 6 is an account of various radiation damage processes that occur in ionic and semiconductor crystals in which there is a brief but illuminating of such technologically important defect processes as latent image formation in photography, photochromic glasses, ion implantation in semiconductor materials and laser annealing. The last two chapters discuss surface properties and related phenomena (sintering. oxidation, corrosion and catalysis) and a panoply of ‘special systems’ (metal-insulator transitions, amorphous solids, glacces, intercalates and polymers) A lot of solid state scientists will enjoy this book; not only is the science interesting, but it’s a good read.

MG Silk, AM Stoneham & JAGTemple - Reliability of Non Destructive Inspection : Assessing the Assessment of Structures under Stress 
Adam Hilger (1987) ISBN 0-85274-533-8


Metals and Materials, May 1988

This is a most welcome book for several reasons. First, because the subject of reliability of nondestructive inspection has be come of growing interest to the majority of engineers and materials experts, particularly those involved in the design, fabrication and operation of welded metal structures. The use of fracture mechanics to assess the integrity of such structures when they may contain crack-like defects has put an emphasis on knowing with some certainty whether and where such defects exist and how large they are. In those applications where a quantitative assessment of the risk at failure needs to be made, its important to be able to include a quantitative assess ment of the abliity of nondestructive inspec on to find any critica’ defects and to know the accuracy of their sizing. Moreover, the importance of nondestructive inspection re liability is not only from a safety viewpoint; there is an important economic aspect be cause the use of an unreliable inspection technique can load to calls for unnecessary, costly and sometimes even damaging repairs. The book discusses the many factors which influence the level of inspection reliability. particularly detailing those related to the use of ultrasonics to detect and size crack-like defects in steel structures, but covering those in a basic way that is re levant to other applications. Not only a the physical factors which can provide limitations on the capability and effectiveness in particular cases of defect detection described in detail, but the book also intro ducos the concepts of risk and system failure analyses, as well as the possible influences of various human factors and of the legal and economic background. A particularly useful chapter on the failure of inspection elaborates on each of the above aspects and concludes with a mathematical description of unreliability which is used to highlight important lessons on how to make improvements. The later chapters of the book discuss the use of test block and so-called round-robin studies to help quantify inspection reliability in specific cases, and these chapters provide valuable new insight into the ways to optimise such studies from a cost-effectiveness viewpoint. The results and implications of some recent test block exercises such as the UKAEA Defect Detection Trials are then discussed. Unfortunately the book was in the proof stages before the results of the important second phase of the CEC/OECD Programme for the Inspection of Steel Components (PISCII) became available, leaving this part of the book somewhat outdated; nevertheless many of the lessons drawn from the earlier studies continue to have considerable importance. The second reason for welcoming this book arises from the authority and insight which it brings to the subiects discussed, resulting from the experience, skills and intelligence which give the three authors their well deserved international reputa tions. But no amount of knowledge on the part of the authors would be of value if it were not communicated to the readers. In this respect too this book is most welcome, the authors expressing themselves enthu siastically in a clear, concise and readable style which has been attractively presented in a well produced volume of about 200 pages. Undoubtedly this very brevity leaves room for further, more detailed and more extensive, treatment of the various topics covered, but the present book cannot fail to interest a wide range of readers who will certainly be provided with a great deal to think about, as well as much information that should help to improve the reliability of applied nondestructive inspection.

Review by R W Nichols


The Structural Engineer, 1986

An excellent book by three members of the Harwell Laboratory, investigating an area where guidance is most welcome. The book will be of assistance, firstly, to those who are having to make decisions based on NDT inspections without necessarily having knowledge of the technological background, and, secondly, to those who are involved with the detail of techniques and who may not be able to assess the confidence that can be placed on their examinations. To clarify the subtitle, the book is concerned with the assessment of structures, whether under stress or not, and not with stress itself. The book covers historical aspects through to the most recent developments, the general objectives of non-destructive testing, and mainly the reliability that can be achieved in the various fields, discussing risk analysis and human factors. Legal, economic and medical aspects are briefly covered, but are ancillary to the main theme. Consideration is given to basis material defects, defects introduced in manufacture, and the monitoring of defects in service. Techniques reviewed include magnetic particle, dye penetrant, ultrasonics, impact, vibration, accoustic, electrical and thermal resistivity, eddy current, magnetic flux, radiography, and proof testing, assuming that it proves non-destructive!

The latter part of the book concentrates on approaches to errors and reliability, mathematical, statistical and probabilistic analysis inspectability, test block comparisons, defect detection trials, and, for those still surviving, the future of round. The book provides a stimulating review and investigation into the reliability of non-destructive investigations, thereby making a valued contribution towards the assessment of safety of structures.
