Abstract

The paper substantiates a physical approach to describing transport phenomena in polycrystalline semiconductor films. The case including the transfer of charge carriers across block boundaries (BB) is considered. The electrical conductivities of the barrier are found in the directions along the axes (perpendicular to the BB) and (parallel to the BB).
