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…

Asymptotics of the trap-dominated Gunn effect in p-type Ge
L. L. Bonilla, P. J. Hernando, M. A. Herrero +2
We present an asymptotic analysis of the Gunn effect in a drift-diffusion model---including electric-field-dependent generation-recombination processes---for long samples of strong…
