Joachim D. Thomsen: In-situ TEM patterning and electrical characterization of graphene

Joachim D. Thomsen, Carsten Gade, Peter Bøggild, Tim J. Booth Department of Micro and Nanotechnology, Technical University of Denmark Transmission electron microscopy is a characterization tool able to obtain atomic scale resolution, and can also be used to nanopattern graphene. We have designed a micro-fabricated platform with on-chip heating and electrical contacts for in-situ environmental TEM characterization and modification of graphene and other 2D materials. We will present our initial results on graphene constrictions and interflake conductance of twisted bilayers. Joachim Dahl Thomsen is a PhD student in the Nanocarbon Group at the Department of Micro and Nanotechnology, Technical University of Denmark (DTU), under supervision of Associate Professor Tim J. Booth and Professor Peter Bøggild. He works with in-situ transmission electron microscopy experiments (TEM) involving patterning and electrical characterization of graphene and other 2D materials, as well as optimization and micro-fabrication of platforms compatible with TEM holders for such experiments. Joachim received his M.Sc. degree in Physics and Nanotechnology from DTU in 2014 where he worked with cleanroom micro-fabrication of flexible arrays of photodetectors in his final project.
