Nano and quantum electronics

Competence

We combine physics, electronics, and nanofabrication expertise to investigate and understand new phenomena in nanoscale structures and to find optimal solutions to challenges in new innovations. Our main competence areas include nanoelectronics, nanophotonics, and applications of Josephson junction devices and circuits, supported by expertise in device fabrication and characterisation. Recent research topics also include molecular electronics based on proteins and graphene and THz imaging.

Challenges

Nanoscale structures and devices are not only interesting research topics, but they provide means to develop new applications. The challenge is to understand the underlying physics determining the behaviour and properties of the new structures. Low temperature quantum devices are used when the ultimate performance is needed as is often the case in security, medical, and space applications.
