WebBand gap. If an energy gap exists in the band structure of a material, it is called band gap. The physical properties of semiconductors are to a large extent determined by their band … Webmeasurements [26–28]. Grain boundaries formed during CVD or MBE growth have different orientations depending upon the twist angles [24, 29]; the grain boundaries are hence associated with uncontrolled local strain and thereby can result in different band gaps. When stacking patterns of CVD grown (bottom-up) and mechanically exfoliated (top-down)
