Contact Properties and Related Conduction Phenomena in Insulating Cadmium Sulfide.

摘要

The static distribution of the electric field in thin insulating crystals of CdS provided with various electrodes was investigated. It was found that,when non-injecting electrodes were used,Contact barriers were formed which have the nature of the usual schottky barriers known to exist on high-conductivity CdS. A pulse photoeffect model was developed that successfully explains the results in terms of contact barriers. The barrier space charge density can be related to the bulk density of centers. The barrier photoeffect model in CdS is dependent on the presence of native defects of relatively high density and electron cross-section.
