Optical characterization and transport measurements on 2D Films with the squeezable nanojunction technique — •Alexander Fuchs, Matthias A. Popp, and Heiko B. Weber — Lehrstuhl für Angewandte Physik, Staudtstraße 7, 91058 Erlangen, Germany

We use the recently developed Squeezable Nanojunction techique [1] for simultaneous optical characterization and transport measurements on vertically contacted 2D-Materials. With our technique we can adjust the distance between two chip surfaces on the atomic scale. Due to the optically transparent nature of our silicon carbide substrate material the technique allows for investigations of the interplay between optical properties and electrical transport phenomena of distance controlled tunneling contacts between Graphene-Graphene, Graphene- MoS₂-Graphene, MoS₂−MoS₂ ... structures. On this poster we present concepts and capabilities of our setup along with first results.
