摘要: Zero‐bias dc negative differential resistance of double barrier quantum well diodes in an ac field is explained. A physical picture presented terms resonant tunneling phenomena. An adiabatic approximation used limiting the present approach to applied frequencies lower than ultimate device speed which order 1 THz for AlxGa1−x As/GaAs devices.
