Effective Nonlinear Model of Resonant Tunneling Nanostructures
Enrique Diez, Angel Sanchez, Francisco Dominguez-Adame
We introduce a model of a nonlinear double-barrier structure, to describe in a simple way the effects of electron-electron scattering while remaining analytically tractable. The mo…
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…
Thomas-Fermi approach to resonant tunneling in delta-doped diodes
Enrique Diez, Francisco Dominguez-Adame, Angel Sanchez
We study resonant tunneling in B--doped diodes grown by Si-molecular beam epitaxy. A Thomas-Fermi approach is used to obtain the conduction-band modulation. Using a scalar Hamil…
Nonlinear Resonant Tunnelling Through Double Barrier Structures
Enrique Diez, Francisco Dominguez-Adame, Angel Sánchez
We study resonant tunnelling through double-barrier structures under an applied bias voltage, in which nonlinearities due to self-interaction of electrons in the barrier regions ar…
