Electron scattering on disordered double barrier GaAs-AlGaAs heterostructures
I. Gomez, E. Diez, F. Dominguez-Adame +1
We present a novel model to calculate vertical transport properties such as conductance and current in unintentionally disordered double barrier GaAs-AlGaAs heterostruc…
Extended states and dynamical localization in the random-dimer model
F. Dominguez-Adame, A Sanchez, E Diez
We study quantum diffusion of wavepackets in one-dimensional random binary subject to an applied electric field. We consider three different cases: Periodic, random, and random dim…
Transport properties of nonlinear double-barrier structures
E. Diez, A. Sanchez, F. Dominguez-Adame
We introduce a solvable model of a nonlinear double-barrier structure, described by a generalized effective-mass equation with a nonlinear coupling term. This model is interesting…
Nonlinear treatment of many-body effects in double-barrier resonant tunneling structures
Enrique Diez, Angel Sanchez, Francisco Dominguez-Adame
We introduce a simple, solvable model of double-barrier resonant tunneling structure which includes the effects of electron-electron and electron-phonon scattering. The model is ba…
