Abstract

Two-dimensional (2D) materials are very promising materials for many applications. Stacking order of the 2D materials has a strong influence in their optical and electronic properties, e. g. the semiconducting bandgap and spin properties of 2-layer and 3-layer MoS2 show strong dependence on its stacking order. While conventional semiconductor devices are fabricated using different materials, i.e. hetero-structures, 2D material-based can be homo-structured utilizing the stacking dependent property. Such devices are made by using the same material, but differ in thickness or in stacking sequence, to perform various functions, e.g. in pn junction, transistors, solar cells and LEDs.
