Abstract
We examine theoretically the dc current-voltage characteristics of semiconductor-insulator multiple quantum wells with localized states in insulator barriers. The current exhibits periodic oscillating behavior for relatively high electric fields due to the resonant tunneling of electrons via these localized states. The time development of such current oscillations is also estimated.
