A contribution to the explanation of the electronic spectrum of amorphous materials

In this article the electronic spectrum is explained on the basis of a polycrystalline model of amorphous material. It is shown that from the given model the origin of the “tail profile” function can be derived which expresses the dependence of the density of states on energy. Taking into consideration the small density of states in the region of the tail, “the increase” of activation energy of amorphous materials in comparison with monocrystalline materials can easily be explained.
