讨论了高斯型载流子分布的静态屏蔽效应及其对空穴—空穴散射率的影响 ,说明随着空穴初始动能的减小 ,载流子分布的静态屏蔽效应和散射前后空穴波函数的重叠积分导致散射率迅速减小 .重叠积分对空穴—空穴散射率带来的修正因子的下限约为 0 3,上限为 1,均大于先前报道的修正因子 0 1.理论计算与实验测量结果符合
The static shielding effect of Gaussian carrier distribution and its effect on the hole-hole scattering rate are discussed. It is shown that the static shielding effect of the carrier distribution and the hole wave before and after scattering The overlapping integral of the function leads to a rapid decrease of the scattering rate.The lower limit of the correction factor caused by the overlap integral on the hole-hole scattering rate is about 0 3 and the upper limit is 1, both of which are larger than the previously reported correction factor 0 1. Theoretical calculation and The experimental results are in agreement
