Klaus Ensslin

Prof. Klaus Ensslin is a Full Professor of Solid-State Physics at ETH Zurich's Department of Physics. His research focuses on mesoscopic systems and semiconductor nanostructures, particularly exploring quantum properties of electrons in graphene-based systems. He holds a doctoral degree from the Max Planck Institute and conducted postdoctoral research at UC Santa Barbara. Notable awards include the Gerhard Hess Prize (1995) and the Edison Volta Prize (2020).

His work emphasizes quantum transport phenomena in nanoscale systems, including graphene quantum dots, spin-valley physics, and superconducting heterostructures. Recent studies involve magic-angle twisted bilayer graphene systems, exploring superfluid dynamics and vortex behavior. Key experimental techniques include scanning gate microscopy and microwave resonator coupling for quantum state characterization.

Ensslin's contributions span semiconductor quantum devices, topological phases, and correlated electron systems. His lab, Laboratorium für Festkörperphysik, develops advanced nanofabrication methods for precision control of electronic properties. Current projects investigate valleytronics, coherent electron jetting, and tunable quantum interferometers in moiré materials.
