Current Instabilities under Millimeter and Submillimeter Electromagnetic Waves Heating in Semiconductors with Negative Differential Conductivity

Abstract

In this article, the formation of static negative differential conductance (NDC) under simultaneous electron gas heating by high-frequency (HF) and static electric fields is studied. As in this case, the heating electromagnetic wave has a pronounced effect on appearance of NDC caused by the overheating mechanisms and on the type of the static current-voltage characteristic (CVC), as a whole.
