"Symmetry-breaking and chaos in electron transport in semiconductor superlattices," cond-mat/0104144. http://arxiv.org/abs/cond-mat/0104144Physica D, 113 (1998) 129-133http://arxiv.org/abs/cond-mat/0104144https://hdl.handle.net/2144/982We study the motion of electrons in a single miniband of a semiconductor superlattice driven by THz electric field polarized along the growth direction. We work in the semiclassical balance-equation model, including different elastic and inelastic scattering rates, and incorporating the self-consistent electric field generated by electron motion. We explore regions of complex dynamics, which can include chaotic behaviour and symmetry-breaking. We estimate the magnitudes of dc current and dc voltage that spontaneously appear in regions of broken-symmetry for parameters characteristic of modern semiconductor superlattices.
