Abstract
A semiconductor material having a disordered structure consists of a semiconductor material on which epitaxial growth is possible. The semiconductor material has an energy band structure constituted by one of the indirect band structure, the direct band structure, and a combination of the indirect and the direct band structures, and consists of a plurality of semiconductor layers. The semiconductor layer is orderly arranged along its surface and disorderly arranged along its thickness direction with respect to at least one of the followings the number of atomic or molecular layers constituting the semiconductor layer, a composition of a specific molecular layer of the molecular layers, and impurity doped to the semiconductor layer.
