The resonant tunnelingofelectrons through a double barrieris analyzed from a dynamical point of view. When a self consistent potential, representing the effect of the electrostatic feedback induced by the charge trapped in the well, is taken into account, the non linearity of the transmission process can lead to oscillations of the transmitted fluxes. This behavior is shown to depend sensitively on the energy spread of the incident electron distribution and on the intensity of the electrostatic feedback.

Abstract
The resonant tunnelingofelectrons through a double barrieris analyzed from a dynamical point of view. When a self consistent potential, representing the effect of the electrostatic feedback induced by the charge trapped in the well, is taken into account, the non linearity of the transmission process can lead to oscillations of the transmitted fluxes. This behavior is shown to depend sensitively on the energy spread of the incident electron distribution and on the intensity of the electrostatic feedback.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
