Ефективна провідність трифазних напівпровідникових гетероструктур

Abstract

This paper analyzes the effective electrical conductivity of three-phase heterogeneous semiconductor structures using the Bruggeman effective medium approach. The model accounts for the influence of depolarization factors, geometrical characteristics of inclusions, and percolation effects on charge transport. A composite system consisting of a crystalline semiconductor matrix and amorphous inclusions of different geometry is considered. The roles of inclusion shape, volume fraction, and connectivity in forming conductive paths are discussed. The presented approach enables estimation of macroscopic electrical properties of complex composite materials
