Speaker-Klaus Ensslin

Klaus Ensslin
ETH Zurich, Switzerland

Dr. Klaus Ensslin has been Professor of Solid-State Physics at ETH Zurich since October 1995. Dr. Klaus Ensslin studied physics at the University of Munich and at ETH Zurich. After completing his doctoral dissertation at the Max Planck Institute in Stuttgart, he was a postdoc at the University of California in Santa Barbara, USA. From April 1991 until September 1995 he worked at the University of Munich. His habilitation thesis was awarded a prize from the University of Munich. In 1995 he received the Gerhard Hess prize of the German Science Foundation promoting outstanding young researchers.

The primary research interest of Dr. Klaus Ensslin lies in the physics of mesoscopic systems. The electronic properties of novel semiconductor nanostructures are investigated using material control down to the atomic scale. One important goal is the ever increasing control and improved understanding of the quantum properties of electrons in nanostructures.

Abstract

The potential and the challenges to realize graphene quantum devices is reviewed. Localized states at the graphene edges can dominate transport for structure with device sizes below 100 nm. These localized states can influence transport even if located far from the direct transport path. Van-der Walls stacked quantum dots reveal mesoscopic Coulomb drag dominated by energy transfer rather than momentum transfer as it is the case for higher dimensional structures. Since graphene quantum devices separated by a thin BN layer are strongly coupled, the effect of measurement back action can be measured and quantified.
