A discrete drift model of sequential resonant tunneling in weakly-coupled doped or undoped GaAs AlAs superlattices (SL) under d.c. or d.c. + a.c. voltage bias and laser illumination is analyzed. In agreement with experiments our model shows an oscill

A theoretical model for the noise properties of n+nn+ diodes in the drift-diffusion framework is presented. In contrast with previous approaches, our model incorporates both the drift and diffusive parts of the current under inhomogeneous and hot-car

When reducing the dimensions of a device, carrier transport goes from diffusive to ballistic regime and both current-voltage characteristics and Johnson-Nyquist noise caused by carrier scattering processes acquire new features. In diffusive regime th

Current fluctuations associated with the classical size effect, for which the mean free path of the carriers \ensuremath{\lambda} is comparable to, or greater than, the film thickness d, have been investigated. The Monte Carlo approach has been exten

Self-sustained time-dependent current oscillations under dc voltage bias have been observed in recent experiments on n-doped semiconductor superlattices with sequential resonant tunneling. The current oscillations are caused by the motion and recycli
