MAXIMIZING THE PERFORMANCE OF PHOTOCONDUCTORS.
Abstract
Hall effect measurements for photogenerated car riers in vitreous Se showed that n-type photo conductivity predominates in illuminated layers, while current is carried mainly by holes in unexcited Se. The electron mobility is 0.32 plus or minus 0.1 cm squared/v s. The formation of precipitates of acceptor impurities in large CdS crystals has been demonstrated for concentra tions as low as 2 x 10 to the -2%, the upper limit for the solubility of Cu in CdS. Cu and Ag sulfides exist as rods at low concentrations. At concentrations near 1%, Cu forms large discs. Au segregates as hexagonal platelets of elemental Au. Inclusions have a particular orientation with respect to the C-axis of CdS. (Author)
