研究了ZnS中的电子声子相互作用 .以此为基础 ,利用MonteCarlo方法研究了ZnS中电子在不同温度下的高场输运特性 .电子加速的瞬态时间基本不随温度变化 .电子的动能分布函数随温度升高向低能方向移动 ,即平均动能降低 .电子在各能谷间的分布随温度升高而向低能谷移动 .电子的漂移速度则随温度升高而降低 .给出了这些物理量随温度变化的具体规律
The electron-phonon interaction in ZnS was studied, and Monte Carlo method was used to study the high field transport properties of electrons in ZnS at different temperatures. The transient acceleration time of electrons did not change with temperature. The kinetic energy distribution of electrons The function moves toward lower energy with increasing temperature, that is, the average kinetic energy decreases.The distribution of electrons in each energy valley moves to low energy valley with the increase of temperature, and the electron drift velocity decreases with the increase of temperature. With the temperature changes in the specific law
