Magnetoswitching of current oscillations in diluted magnetic semiconductor nanostructures
R. Escobedo, M. Carretero, L. L. Bonilla +1
Strongly nonlinear transport through Diluted Magnetic Semiconductor multiquantum wells occurs due to the interplay between confinement, Coulomb and exchange interaction. Nonlinear…
Multiquantum well spin oscillator
L. L. Bonilla, R. Escobedo, M. Carretero +1
A dc voltage biased II-VI semiconductor multiquantum well structure attached to normal contacts exhibits self-sustained spin-polarized current oscillations if one or more of its we…
Voltage switching and domain relocation in semiconductor superlattices
L. L. Bonilla, R. Escobedo, G. Dell'Acqua
A numerical study of domain wall relocation during voltage switching with different ramping times is presented for weakly coupled, doped semiconductor superlattices exhibiting mult…
Wigner-Poisson and nonlocal drift-diffusion model equations for semiconductor superlattices
L. L. Bonilla, R. Escobedo
A Wigner-Poisson kinetic equation describing charge transport in doped semiconductor superlattices is proposed. Electrons are supposed to occupy the lowest miniband, exchange of la…
Generalized drift-diffusion model for miniband superlattices
L. L. Bonilla, R. Escobedo, A. Perales
A drift-diffusion model of miniband transport in strongly coupled superlattices is derived from the single-miniband Boltzmann-Poisson transport equation with a BGK (Bhatnagar-Gross…
Free boundary problems describing two-dimensional pulse recycling and motion in semiconductors
L. L. Bonilla, R. Escobedo, F. J. Higuera
An asymptotic analysis of the Gunn effect in two-dimensional samples of bulk n-GaAs with circular contacts is presented. A moving pulse far from contacts is approximated by a movin…
