Absolute negative conductivity and zero-resistance states in two dimensional electron systems: A plausible scenario
arXiv:cond-mat/0408229 · doi:10.1134/1.1825124
Abstract
We present a model which provides a plausible explanation of the effect of zero-resistance and zero-conductance states in two-dimensional electron systems subjected to a magnetic field and irradiated with microwaves observed in a number of experiments and of the effect main features. The model is based on the concept of absolute negative conductivity associated with photon-assisted scattering of electrons on impurities. It is shown that the main features of the effect can be attributed to the interplay of different electron scattering mechanisms.
