Welcome... the website of the UCL Organic Semiconductors group!

Here you will find information about us, our current and past work, the facilities available to the group and details of vacancies and available PhD projects if you're interested in joining us. We also have information on accommodation in London for new, prospective and visiting students and staff, and links to external webpages relevant to our work.

If you want to get in touch, head to our contacts page.

Our group works on organic semiconductors and related nanostructures. Experimental facilities include those for processing and characterisation of organic semiconductors devices as well as for fabrication and investigation of organic semicon ductors nanostructures by means of a home-built scanning near-field optical microscope (SNOM). Additional, shared research facilities accessible by the group within the London Centre for Nanotechnology (LCN) include a fully equipped clean room, access to a focused-ion-beam (FIB), 3 scanning probe set-ups (AFM/STM), electron-beam and optical lithography. The group is also active in international collaborations with Canada, Germany, Belgium, Holland, France, Italy, Poland, Portugal, Spain, Sweden, and Japan. Some of these interactions are also funded by a recently funded Marie-Curie Research Training Network dedicated to the development of threaded molecular wires (THREADMILL) and by the Self-Organised Nanostructures II - SONS2 initiative of the European Science Foundation (ESF), that is supporting the SUPRAMATES (SUPRAmolecular MATerials for new functional StructurES) project.
