Abstract
The excess noise with respect to the simple shot noise is calculated for a single quantum well. device characterized by a modulation mechanism of the current transport process at the emitter potential barrier. The effect of the negative space charge on the noise is taken into account and it is shown that it acts as a smoothing factor for the shot noise but it is not influent on the excess noise generated by the barrier fluctuations.Pubblicazioni consigliate
