Enrique Diez is a full professor of Theoretical Physics at the Department of Fundamental Physics at Salamanca University. He is the Director of the Nanotechnology Group and Head of the  Clean Room and Low Temperature Laboratories. Enrique Diez, was born in Luzern (Switzerland)  in 1969 and obtained his Ph.D. in Physics by University Carlos III of Madrid in 1997. He continued his postdoctoral studies with Prof. Daniel Tsui (Nobel Prize in Physics) in Princeton University with a MEC-Fulbright fellowship.  He engaged to  the University of Salamanca by January 2004 under the program “Ramón y Cajal” (a national programme to reduce the loss of talent and improve the number of groups of excellence in Spain). From December 2010 as an Associate Professor and from August 2019 as Full Professor of our Sciences Faculty. During the last ten years he has devoted great efforts to the installation of a new Clean Room facility designed for graphene based nanoelectronic devices. He also head the settle up of the first in Europe 100% Cryofree Low Temperatures Laboratory for magneto transport characterization (12 Teslas and 10 milikelvin). He has focused his research in the transport and electronic properties of quantum nanosystems particularly 2D systems in the extreme quantum limit (high magnetic fields and dilution temperatures).  He is currently researching unconventional 2D materials including graphene heterostructures and topological insulators looking for unique physical properties bearing in mind their uses in novel optoelectronic devices for the generation and detection of sub-THz and THz radiation to be used in a wide range of applications (Communications, Healthcare, Security, Life Sciences). He focus now his research in broken symmetry nanomaterials (twisted 2D materials) and the use of quantum point contacts for reveal exotic quantum features as viscous flow and chiral electronics.
