Christian Schönenberger holds a degree as an electrical engineer in applied sciences (1979) and a diploma in physics (1986). He did his PhD at the IBM Zurich Research Lab in the group of Dr. H. Rohrer and Dr. S. Alvarado. His PhD is entitled "Understanding Magnetic Force Microscopy" which was awarded with a medal from the ETH-Zurich and the Swiss Physical Society price (1991). Subsequently, he worked at the Philips Research Lab. at Eindoven (NL), first as a postdoc, and later as a permanent staff member. In 1994 he was awarded a fellowship from the Swiss National Science Foundation (Profil-II). Soon afterwards he was elected to a full chair at the Univ. of Basel (1995). Since then, Christian Schönenberger has setup a group whose research focuses on charge transport in nanoscaled devices. He has co-authored over 80 refereed journal publications. He has participated in several EU programs and is currently directing the Swiss Nanoscience Institute at the University of Basel and the Swiss-NSF center on Nanoscale Science and Technology: http://www.nanoscience.ch.

The nanoelectronics group is interested in fundamental electrical properties of engineered nanoscaled devices operating in the quantum regime. We probe these devices by electrical transport measurements both at low (close to DC) and high frequency (GHz range) and at cryogenic temperatures (Kelvin to milli Kelvin). Our devices are based on novel materials with reduced dimensions, either one-dimensional carbon-nanotubes (CNTs), quasi one-dimensional semiconducting nanowires (NWs) or two-dimensional graphene and vand der Waals heterostructures which are defined by state-of-art e-beam lithography and complemented with gate and contact electrodes. The group is internationally recognized as a leader in so-called hybrid quantum devices that embody in addition to normal metal also superconducting and ferromagnetic electrodes. The latter introduce non-trivial correlations by proximity effect, such as a pairing or exchange field. In combination with intrinsic properties and surface effects, new correlated many-body states can arise. Examples are topological states such as the spin-helix states in one-dimension, molecular Andreev-bound states and Majorana-like states. In addition, we are working on suspended ultraclean devices that can additionally be driven mechanically allowing to explore the coupling between mechanical and electrical degrees of freedom at the quantum limit.
