TAILS OF THE DENSITY OF STATES AND HALL EFFECT IN NON-CRYSTALLINE MATTERS

By Efim Petrovich German

Abstract

The theoretical investigation of the density of localized states in non-crystalline matters and low-dimensional structures is the aim of the paper as well as the investigation of the mechanism of Hall effect in various regimes of jamp conduction. It has been shown, that tails of the density of states in non-crystalline matters depend on the temperature pre-history of a sample. It has been shown, that tails of the density of states in low-dimensional narrow-zone structures are suppressed strongly. The possibility of the property regulation for non-crystalline semiconductors with the help of thermal treatment has been revealed. Theoretical forecastings of the Hall mobility and typical geometrical sizes, characterizing Hall effect, have been obtained. The theory of tails of the density of states and Hall effect in non-crystalline matters is being used for the determination of parameters of a material electron structure. The paper results may find their field of application in physics of non-ordered semiconductors, dielectrics and polymers, physics of low-dimensional structuresAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
