Negative Electric Current in Semiconductors
arXiv:cond-mat/9801097 · doi:10.1016/S0375-9601(97)00731-7
Abstract
Electric current in semiconductors is considered as a function of time. Nonequilibrium fluctuations of the current are studied for strongly nonuniform samples. It is demonstrated that at special conditions the total electric current through a device can exhibit a negative fluctuation, when the current is directed against the applied voltage.
