Complete Analysis of a transmission electron diffraction pattern of a molybdenum disulphide-graphite heterostructure — •Marlene Adrian, Arne Senftleben, Silvio Morgenstern, and Thomas Baumert — University of Kassel, Institute of Physics (CINSaT), D-34132 Kassel, Germany

The combination of various 2D layered materials in multilayer heterostructures arises great interest in the current science. Due to the large variety of electronic properties in the group of 2D layered materials, the combination opens a new pathway towards ultrasmall electronic devices. In this contribution we present a complete mathematical description of multilayer heterostructures and a full characterisation of their diffraction patterns. A 27 nm thick molybdenum disulphide-graphite heterostructure was produced and analysed with the methods presented. Additionally, the ultrafast lattice dynamics after optical excitation of the sample will be discussed.
