Spin-polarized current oscillations in diluted magnetic semiconductor multiple quantum wells
Manuel Bejar, David Sanchez, Gloria Platero +1
We study the spin and charge dynamics of electrons in n-doped II--VI semiconductor multiple quantum wells when one or more quantum wells are doped with Mn. The interplay between st…
Field-domain spintronics in magnetic semiconductor multiple quantum wells
David Sanchez, A. H. MacDonald, Gloria Platero
We develop a theory of non-linear growth direction transport in magnetically doped II-VI compound semiconductor multiple-quantum-well systems. We find that the formation of electri…
Photoassisted dynamical transport in multiple quantum wells
Rosa Lopez, David Sanchez, Gloria Platero
We study the dynamical transport in weakly coupled superlattices in the presence of intense radiation in the THz regime. We derive a general model for the time dependent tunneling…
Temperature dependence of current self-oscillations and electric field domains in sequential tunneling doped superlattices
David Sanchez, L. L. Bonilla, G. Platero
We examine how the current--voltage characteristics of a doped weakly coupled superlattice depends on temperature. The drift velocity of a discrete drift model of sequential tunnel…
Quasiperiodic time dependent current in driven superlattices: distorted Poincare maps and strange attractors
David Sanchez, Gloria Platero, Luis L. Bonilla
Intriguing routes to chaos have been experimentally observed in semiconductor superlattices driven by an ac field. In this work, a theoretical model of time dependent transport in…
Microscopic derivation of transport coefficients and boundary conditions in discrete drift-diffusion models of weakly coupled superlattices
L. L. Bonilla, G. Platero, D. Sanchez
A discrete drift-diffusion model is derived from a microscopic sequential tunneling model of charge transport in weakly coupled superlattices provided temperatures are low or high…
