Nano group of the Low Temperature Laboratory investigates fundamental quantum phenomena in nanostructures using low temperature and electronic transport measurements. In both normal and superconducting nanosamples quantum mechanical wave character of the electrons and their Coulomb repulsion lead to new phenomena, which we try to utilize in new sensor/amplifier applications.

We have developed, among others, record-sensitive single electron transistor (SET) components made out of carbon nanotubes and nearly back-action-free, reactively read superconducting electrometers. In addition, we have developed a novel, low-noise current amplifier, Bloch oscillating transistor, which lies between the superconducting quantum interferometer (SQUID) and the SET according to its characteristics. We also work on graphene field effect devices.

The Nano group is involved in several European projects such as Graphene Flagship and Interfacing Quantum Optical, Electrical, and Mechanical Systems (iQUOEMS), both  sponsored by the European Commission. We also benefit from several national and international bilateral collaborations.
