Prof. Franco Cacialli

Franco Cacialli

Franco works on organic semiconductors and related nanostructures and is a member of both the London Centre for Nanotechnology and the Department of Physics and Astronomy at UCL. He obtained his PhD from the University of Pisa and later worked in Cambridge on the physics of electroluminescent polymers and related devices. His research has ranged from the set-up of an original chemical vapour deposition method of heavily doped conducting polymers to the study of polymer LEDs and the control of their luminescent properties in optical microcavities. Recent interests include supramolecular architectures for the control of the solid-state properties of organic semiconductors, and high-resolution nanolithography using the scanning near-field optical microscope (SNOM).

PhD Students

Francesco Bausi

Francesco is a third year PhD student funded by a Marie Curie Fellowship for Early Stage Research Training in the network GENIUS (GraphenE-orgaNIc hybrid architectures for organic electronics: a mUltiSite training action). He is working on the optimization and the characterization of graphene sheets depositions for the fabrication of electrodes for PLED, OPV cells and Organic Transistors. His research also involves optical and thermal lithographic patterning techniques for the development of graphene based electrodes with tuneable work function.

He can be found on level 3 of the LCN or contacted using the details below:

Giulia Tregnago

Giulia is a third year PhD student. Her research is focused on graphene-based materials for optoelectronic applications. She is investigating the chemical and physical properties of these materials using steady-state and time-resolved photoluminescence spectroscopy, AFM, Kelvin probe and lithography techniques. Furthermore, she is testing the graphene-based materials into optoelectronic devices (i.e. polymer solar cells, organic light-emitting diodes). Giulia is funded by the Marie Curie Initial Training Network GENIUS.

She can be found on level 3 of the LCN or contacted using the details below:

Giuseppe Paternò

Giuseppe is a third year PhD student. He has a background in chemistry, since he obtained a bachelor in Chemistry and a master degree in Chemistry of Materials at University of Catania. His research focuses on organic solar cells, with a view to optimize cell efficiency and long term stability. For this purpose, his work is devoted to the characterization of PV properties using the facilities at UCL, and to structural/dynamical investigation using a range of Neutron Scattering techniques at ISIS (UK). Furthermore, he studies the effect of radiation exposure on cell performance with the instrumentation available at ISIS.

He can be found in room F9 in the Physics and Astronomy Department (UCL) or contacted using the details below:

Valentina Robbiano

Valentina is a second year PhD student. She is funded by a Marie Curie Initial Training Network CONTEST (COllaborative Network for Training in Electronic Skin Technology). She obtained a Masters degree in Materials Science and Engineering at the University of Genova. Her work is focused on the preparation and characterization of photonic systems suitable for flexible optoelectronic devices. This work will include different preparation methods as well as different optical-morphological characterization techniques such as polarized transmittance and reflectance angle resolved spectroscopy, steady-state and time-resolved photoluminescence spectroscopy and AFM.

Luca Santarelli

Luca Santarelli is a first year PhD student. He is funded by a Marie Curie Initial Training Network CONTEST (COllaborative Network for Training in Electronic Skin Technology). He received a BSc degree in Biomedical Engineering and MSc in Electronic Engineering from the University of Pisa. From September 2012 until May 2013 he did an internship at University College London (UCL) funded by the European Erasmus Placement project. Luca’s research is mainly focused on development and characterization of organic devices, such as p-LED, solar cells and sensors, made on flexible and stretchable supports; investigation into properties of electrodes made by carbon nanotubes; thermal and optical lithography of polymer semiconductors through Scanning Thermal Microscopy (SThM) and Scanning Near-field Optical Microscopy (SNOM).
