Influence of dielectric permeability of polycrystal material on the transparency of a potential barrier

Аннотация

Until now, the physical mechanisms responsible for the mechanical, electrical, optical and other properties of solids with a polycrystalline structure have not been fully established.As noted, the problem lies in the complexity of identifying the nature of grain boundaries (GBs) and their real structure, although, for example, it has long been known that many physical phenomena are caused precisely by the presence of GBs and their properties. It can also be pointed out that the optical anisotropy of metal films and polycrystalline semiconductor films, in our opinion, is also related to the structural features of GBs.We are studying an interesting effect observed in polycrystal.
