Nano Theory
Nano theory group is part of the nanoelectronics research in the Low Temperature Laboratory. We have an active collaboration with the experimental Nano, Pico and NEMS groups of the laboratory, but most of our projects are independent of these groups.
Research topics
Our recent topics of research include
- Thermal effects in electronic nanostructures
- Mesoscopic superconductivity, in particular superconducting proximity effect
- Fluctuations of current and temperature
- Far-from equilibrium effects
- Transport through graphene
- Nanoelectromechanical systems
- Topological matter
- Spin-dependent heat transfer in solids
... And combinations of them
Open positions
We have an opening for a post-doctoral position, see the announcement here
We are constantly looking for talented people for doctoral student positions. If you are interested, send email to Tero Heikkilä (firstname.surname@aalto.fi).
