Then the micro-state and transport process of carriers (hot-electron) in vivo of the switch material were studied in details using the quantum theory. It was found: in the DC bias electric field, under the certain condition of the relaxation time of the hot-electrons in the electron-electron and electron-phonon interaction process, the photoconductivity oscillation can be caused by the change of mobility in the process of optoelectronics transport, and the main causes that the output electrical pulse appears oscillation was revealed.
