摘要
对ＣｄＳ薄膜用不同浓度的ＣｄＣｌ２溶液处理后在不同温度下退火，发现其暗电导率σｄ和电导激活能Ｅａ随ＣｄＣｌ２溶液的浓度和退火温度的不同而不同，而且用ＣｄＣｌ２处理再退火的样品，暗电导率σｄ随温度Ｔ变化的关系（ｌｎσｄ１０００／Ｔ）为分段直线，对应于不同的Ｅａ．本文就上述结果进行了讨论，并用Ｃｌ－的扩散进行了解释．
The effect of CdCl 2 treatment and annealing temperature on the electrical properties of CdS films has been studied. The differences in dark conductivity and activation energy of CdS films are caused by the different concentrations of CdCl 2 solutions at the differently annealing temperatures. For the annealed samples treated by CdCl 2, the relation between their dark conductivity and the temperature consists of two straight lines, which correspond with two different activation energies. Discussion on the results is given.
