Fabrication of twisted graphene heterostructures: Different layer sequences and novel device configurations — •Benjamin Gajeufsky, Xiao Xiao, Sung Ju Hong, Christopher Belke, and Rolf J. Haug — Institut für Festkörperphysik, Leibniz Universität Hannover, Hannover, Germany

Twisted bilayer graphene (tBLG) is a representative van der Waals heterostructure, which shows various electronic properties depending on the twist angle. To date, the heterostructures have been constructed using monolayer graphene. Therefore, heterostructures which consist of different ingredients such as bilayer or trilayer graphene remain elusive. Furthermore, since the observable quantities are also limited to conventional transport properties, distinct measurement configurations may reveal novel kind of electronic properties. Here we expand the twisted graphene heterostructure in terms of different layer sequences or device configurations.
