报告内容简介:Following the extensive research work on graphene, a lot of attention has now been focused on two dimensional transition metal dichalcogenide (2D TMD) materials which can in principle compensate some of the disadvantages of graphene, such as lack of a energy bandgap. 2D TMD often show very strong layer-dependent properties. For example, their properties can be strongly influenced by the stacking of the layers, the relative orientation of the layers and the number of layers. Detailed understanding of the inter-layer interaction will help greatly in tailoring the properties of 2D TMD materials for applications. Raman/Photoluminescence (PL) spectroscopy and imaging have been extensively used in the study of nano-materials and nano-devices. They provide critical information for the characterization of the materials such as electronic structure, optical property, phonon structure, defects, doping and stacking sequence.
