A method is proposed to accurately determine the electric-field impact on a
p-n junction. The generation current component is separated from the total
leakage current, with correction for the reverse-bias-dependent diffusion
current. The sources of the electric-field enhancement are considered. The
type of the dominant center, its distribution and energy, the local electri
c field due to imperfections, and the mechanical stress are determined. (C)
