Inductive current and conductive current in photoconductor switches
光导开关中的感生电流与传导电流

Electric pulse of photoconductive switches is determined by transmission character of photo-generated carriers.In the course of transmission,inductive current on the electrodes is formed by photo-generated carriers with high drift speed.Conductive current is formed only after the carriers are absorbed by electrodes.Inductive current and conductive current are calculated by numerical method in this paper.The result shows that inductive current cannot play a main part in the photoconductive switches' output pulse unless under abnormal test conditions.And explaination of ultra-fast rise time of out put pulse faster than the time of carriers to pass between two electrodes with saturated drift speed is given.
