Abstract

An analytic model is proposed to determine the effects of heterointerface properties on the current-voltage and 1/f noise characteristics of forward and reverse biased abrupt heterodiodes. The model suggests: that the 1/f noise is determined by the space charge region recombination process at small forward biases and by the minority carrier diffusion process at moderate forward biases.
