Balkanski, M; Waldron, R D

The spectral response of photoconductivity of ZnS and CdS for both single-crystal and sintered-powder samples was measured for several distances between the area of illumination and the electrode region. The energy transport process for indirect illumination was studied by measuring the photocurrent pulses produced by high intensity light flashes and by experiments with light transmission and electric fields. These studies demonstrate energy transport by electrically neutral entitles other than photons, whlch are interpreted as diffusion of excitons or mobile electron-hole pairs. (auth)
