Voltage Controlled Harmonic Oscillation around 1THz in Resonant Tunneling Diodes Integrated with Slot Antennas

The third harmonic oscillation around 1 THz at room temperature and its frequency change with bias voltage were observed in GaInAs/AlAs double-barrier resonant tunneling diodes integrated with slot antennas. The frequency changed from about 0.96 to 1.02 THz. Theoretical analysis using simple equivalent circuit was in reasonable agreement with the measurement
