摘要:
An exhaustive study of the photodielectric response of proustite at various temperatures over the frequency range 10−2–103Hz has revealed an extremely complex series of changes. These involve both negative and positive photoeffects which appear to arise from competing processes in the sample. A model based on a two‐layer dielectric system, in which one of the layers is established by space‐charge buildup at the electrode, appears to explain most of the observed results.
