Dynamics of Electric Field Domains and Oscillations of the Photocurrent in a Simple Superlattice Model

L. L. Bonilla, J. Galan, J. A. Cuesta +2

A discrete model is introduced to account for the time-periodic oscillations of the photocurrent in a superlattice observed by Kwok et al, in an undoped 40 period AlAs/GaAs superla…
