PRODUCTION AND ANNEALING OF INTRINSIC DEFECTS IN X-RAY IRRADIATED CDS SINGLE CRYSTALS.

Abstract

X-rays (300 keV) have been used to produce changes in the defect structure of (1) 'pure' single-crystal platelets of CdS and (2) platelets which have been pre-heat treated in the vapor of one of its components. The changes were studied by means of the spectral distribution of photocurrent and T.S.C. curves. All measurements were made in ultrahigh vacuum (10 to the -10th power Torr). The damage produced annealed at temperatures between 100 and 150C. The reproducible damage-annealing cycle has been explained in terms of intrinsic defects produced in the sulfur sublattice. Damage-annealing cycles for crystals pre-heat treated in Cd or S vapor (stoichiometry shift) provide additional confirmation for the proposed model. (Author)
