Unified model for p-n junction current-voltage characteristics



Current-voltage p-n junction characteristics have been analyzed mainly at low injection levels. The high injection level region of the I/V characteristic allows the possibility of determining basic parameters of the semiconductor material, like the bulk doping concentration and charge carrier lifetime. Based on a new theoretical model of the p-n junction characteristics, valid for both low level and high level regions, a new general equation of the p-n junction is presented. It can serve for parameter extraction of semiconductor devices.
