OUR RESEARCH IN A FEW WORDS:

We use nano-electronic devices to investigate microscopic electronic processes in different classes of materials, with the aim to push further our fundamental understanding of their electronic properties, to discover new physical phenomena, and to contribute to the development of new practical electronic applications.

Our work include the device nano-fabrication -for which we often develop new technological processes-, transport measurements as a function of temperature, magnetic field, bias- and gate-voltage, etc. We also take care of the data analysis, often seeking the assistance of theoreticians having experience in the field of our experiments. We consider the link between experimental and theoretical part of our research to be particular important, not only for the data analysis, but also for the planning of new experiments. Sometimes, we also contribute to theoretical developments.

In the past, our work has spaced through a broad variety of electronic materials, including hybrid systems with superconductors and ferromagnetic contacts, carbon nanotubes, InAs-base two dimensional electron gases with Rashba spin-orbit interaction, and more. Currently our activity is mainly focused in the areas of graphene-based electronics and organic single-crystal devices, but we are always keen to start working in new emerging areas, whenever we think that with our skills and expertise we can give useful contributions. Please look at our publications to have a more specific idea of our work.

The activity in Geneva has started only recently, but we already have the needed infrastructure in house. This includes e-beam lithography (Raith50 system), e-beam evaporation, ac magnetron sputtering, and a clean-room. We also have organic crystal growth set-ups and different system for their unconventional processing, as it is need for working in the area of organic single crystal electronics. Infrastructure for low-temperature measurements include a dilution refrigerator, a He3 system, several variable temperature inserts including a variable temperature probe-station. In the group magnets up to 14/16 Tesla are available and in our department we can gain access to a 21 Tesla magnet.
