Transmission Electron Diffraction on a really free-standing heterostructure and analysis of the resulting Moiré pattern — Marlene Adrian, •Arne Senftleben, Silvio Morgenstern, and Thomas Baumert — Institut für Physik und CINSaT, Universität Kassel, Heinrich-Plett-Straße 40, 34132 Kassel

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 of the group of 2D layered materials the combination opens a new pathway towards ultrasmall electronic devices. In this contribution we present a preparation method to obtain free-standing samples of multilayer heterostructures and a full characterisation of their diffraction images. A 20 nm thick MoS₂–graphite heterostructure was produced and analysed with the methods presented. Additionally, the ultrafast lattice dynamics after optical excitation of the sample will be discussed.
