Abstract:
A resonant tunneling structure for generating oscillation with multiple fundamental oscillation frequencies is provided. A first quantum well layer has a second sub-band (E2). A second quantum well layer has a first sub-band (E1) and a third sub-band (E3). When no electric field is applied, the resonant tunneling structure satisfies “(Eb1, Eb2)
