Abstract: The results of the photovoltaic detection of P-N junctions with different bias voltages under the illumination of periodically modulated laser are presented in experiment and theory. The static and dynamic photovoltaic images of semiconductor P-N junction devices are obtained by photoelectric microscopy.The studies of the phybsical mechanism of the photovoltaic detection of semicon-ductor P-N junctions provide effectively the analytical foundations of the static and dynamic photovoltaic images of integrated circuits.

Key words: semiconduetor P-N junctions, photoelectric effect, photoelectic imaging
