BANDS STRUCTURE OF 3D and 2D Ca<sub>2</sub>Si
Abstract
The results of theoretical research of band structures of Ca2Si bulk and Ca2Si thin films with surfaces (001), (010), (100) are presented. It`s found that Ca2Si bulk and thin film Ca2Si(010) and (100) are direct bandgap semiconductors while Ca2Si(001) thin films show the metallic properties because of surface`s states.
