In order to eliminate the defects , especially te precipitates , cd1 - xznxte slices were annealed in cdzn vapor in the present researches . the variation of te - rich phases in morphology and sizes during the annealing and its effects on the optical and electrical properties of the crystals were examined in detail . the defect chemistry calculations were made 本文的主要內(nèi)容就是研究退火過程中cd _ ( 1 - x ) zn _ xte晶體內(nèi)富te相的形態(tài)、大小的變化及其對晶體光、電性能的影響,并通過缺陷化學(xué)計(jì)算,結(jié)合實(shí)際的退火實(shí)驗(yàn),制定相應(yīng)的退火工藝,改善晶體性能。
