Defects and Their Role in Determining Bulk Properties of Crystals.
Abstract
The luminescence and electrical properties of doped II-VI compounds have been related to the presence of specific impurity centers by identifying the center through its characteristic paramagnetic resonance and correlating resonance intensity with optical/electrical properties. Because the Jahn-Teller effect is found to occur for many of these impurity defects, it has been studied in simplified situations, Sc(2+) (3d1) in CdF2 and 0(-) (2p5) in KI. Self-activiated, copper, rare-earth, transition metal, and Group V centers are among the impurities studied. P-type ZnSe was produced by P and As doping. Shapr line rare earth fluorescence is excited via energy transfer in a (rare earth)(3+) -4Cu(+) complex. (Author)
