We have discessed the steady—state space—charge—limited currents through a high resistivity semiconduoting CdS crystals. We obtained a quadratic relation between the current and the voltage in the following two eases that the traps are either partially filled or completly filled with electrons, thus we verified the theory developed by lampert and others by experiments. Finally, we analysed the experimental results according to the theory of space-charge-limited currents. The traps concentration and its energe...

We have discessed the steady—state space—charge—limited currents through a high resistivity semiconduoting CdS crystals. We obtained a quadratic relation between the current and the voltage in the following two eases that the traps are either partially filled or completly filled with electrons, thus we verified the theory developed by lampert and others by experiments. Finally, we analysed the experimental results according to the theory of space-charge-limited currents. The traps concentration and its energe level thus determined are, for a typical sample, N_t=2.8×10~(13)cm~(-3). and E_c-E_t=0.35 ev. respectively.

本文研究了通过高阻半导体CdS單晶的定态空間电荷限制电流。得到的电流——电压曲线分成三个明显区域:(1)陷阱未填滿的修正Mott-Gurney平方定律区;(2)陷阱填满极限区;(3)陷阱效应可以忽略的Mott-Gurney平方定律区。对典型样品的电流——电压曲线进行了分析,确定了所含陷阱的密度及其在禁带中的位置。

The effect of temperatures and humidities on development and fecundity of Amblyseius vulgaris were studied.25℃ was the optimum temperature.At 25℃,the mean total developmental time of female from egg to adult was 5.16 d;the longvity of female was 34.16 d;oviposition duration was 21.85 d;mean daily fecundity/female was 45.62 and r_m=0.259.Relative humidity did a great effect on egg hatching and larva survival.When relative humidity lower 43%,egg couldn't hatch.
