Abstract:

Characteristic layerlike field inhomogeneities are shown to occur in homogeneous semiconductors if the decrease in conductivity is stronger than linear with increasing field, and are discussed under a general aspect in a model using Poisson- and transport-equations and the fact that the neutral density of electrons andor the mobility decreases with increasing field strength. The method of characteristics is used for discussion and permits an analysis of the experimental observations easily. Further experimental results about layerlike field inhomogeneities in CdS concerning domain-width and field strengths, influence of optical excitation and quenching, and net charging of CdS crystals are given and show good agreement with the proposed theory.
