本文从ａ—Ｓｉ∶Ｈ的材料特性出发，采用更为精确的ａ—Ｓｉ∶Ｈ带隙态分布模型计算了ａ—Ｓｉ∶ＨＣＣＤ的转移特性，得出了ａ—Ｓｉ∶Ｈ材料参数对ａ—Ｓｉ∶ＨＣＣＤ的动态特性影响的数值分析结果．理论结果表明，ａ—Ｓｉ∶Ｈ材料带隙中的局域态分布对ａ—Ｓｉ∶ＨＣＣＤ的转移特性有非常大的影响．而且在高频下，ａ－Ｓｉ∶Ｈ中的带尾态对ａ—Ｓｉ∶ＨＣＣＤ转移特性的影响比深局域态要大．
Based on the material properties of a-Si: H, a-Si:H band gap distribution model is adopted to calculate the transfer characteristics of a-Si: The results of numerical analysis of the influence of dynamic characteristics of -Si: HCCD. Theoretical results show that the local distribution of a-Si: H bandgap has a very large effect on the transfer properties of a-Si: HCCD. Moreover, at high frequencies, the band-tail a-Si: H has a greater effect on the a-Si: HCCD transfer than the deep-ground state.
