Electrical Conductivity in the Vitreous As-Se-Ge System

  • Rudol’f L. Myuller
Chapter

Abstract

The electron conductivity of a solid is essentially determined by its chemical nature; that is, primarily by its composition and the nature of the chemical bonds between its atoms. In order to resolve the problems of solid state electrochemistry it is essential to study vitreous solids. It is known that the vitreous state is closely associated with the presence of mainly short range valence bonds and the absence of an ordered crystalline structure in the solid. The latter helps to remove the effects of mechanical defects which are statistically difficult to control. The disordered three-dimensional network structure of covalently bonded atoms in a stable vitreous solid is particularly amenable to the application of the principles of statistical physics. It is very interesting, from this point of view, to study the conductivity of the Ge-As-Se vitreous system. As these elements belong to the principal IV to VI subgroups and occupy the neighboring positions 32-33-34 in the Periodic Table, the atomic interactions are mainly covalent and produce an extensive glass-forming region.
