Impact of traps on current-voltage characteristic of n+-n-n+ diode
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2017, Vol 20, Issue 2
Abstract
A model of n+-n-n+ diode is analyzed using analytical and numerical methods. First, it was conducted a phase-plane analysis, which was aimed at further calculations for low and high injection approximations. A numerical method was used to calculate changes of the field, bias and concentration throughout the diode for different current values. Expected impoverishment of free-charge carriers near the anode, and enrichment near the cathode was observed. Current-voltage characteristics were built for different concentrations of traps in base. Increasing bias for same value of current with increasing traps concentration was predicted.
