Abstract
The spectral density of the current fluctuations in a resistor is derived under conditions where the time between collisions or traps has a finite variance. When the variance is infinite, a 1/f type of spectral density can result. It is shown that in both cases a term appears which is given by Nyquist's theorem: in the presence of an applied field the noise intensity is increased at all frequencies. The effect is particularly pronounced if the variance of the intertrapping time is infinite, and the intensity of the current fluctuations is virtually the same as that predicted by a model involving carrier motion in one direction only.This publication has 4 references indexed in Scilit:
