The built in potential ( or barrier potential ) for pn junctions is given by following relation, Vbi = Vt ln (Na*Nd/ni²) which is normally of the order of 0.6V to 0.8 V. It can be seen that Vbi is purely function of Temperature and Doping and independent of the external bias. 網頁Wen Huei Chiou, Hsi Jen Pan, Rong Chau Liu, Chun Yuan Chen, Chih Kai Wang, Hung Ming Chuang, Wen Chau Liu
