On the Photorefractive Gunn Effect
L. L. Bonilla, M. Kindelan, P. J. Hernando
We present and numerically solve a model of the photorefractive Gunn effect. We find that high field domains can be triggered by phase-locked interference fringes, as it has been r…

Electrically tunable GHz oscillations in doped GaAs-AlAs superlattices
J. Kastrup, R. Hey, K. H. Ploog +5
Tunable oscillatory modes of electric-field domains in doped semiconductor superlattices are reported. The experimental investigations demonstrate the realization of tunable, GHz f…

Periodic generation and propagation of traveling fronts in dc voltage biased semiconductor superlattices
Luis L. Bonilla, Manuel Kindelan, Miguel Moscoso +1
The continuum limit of a recently-proposed model for charge transport in resonant-tunneling semiconductor superlattices is analyzed. It is described by a nonlinear hyperbolic integ…
