| 摘 要： | 目前,主要流行的两类微观机制模型——“负有效相关能模型”和“断键模型”——都表明a-Si:H的光诱导变化与其微观结构有关.本文研究了不同制备工艺条件对a-Si:H微结构的影响,和样品的光电导衰退依赖于微结构的关系.最后,从S—W效应的微观机制作了简短讨论.

| Abstract: | We have studied the light-induced degradation of photocenductivity in undoped a-Si: H films and analysed their microstructure by infrared vibraticnal absorption spectra. The experim ental results have shwon that the increase of substrate temperature result in the decrease of the microstructure in a-Si: H films but the effect of the discharge powers is not obvious. The degradation of photoconductivity in a-Si: H films has concern with their microstn.cture during the initial Stage of light exposure. Lastly, the results are triefly aiscussed by the niicicseoprical mechanism of |
