Recent Progress of Terahertz Technology Based on Resonant Tunneling Diode
Resonant Tunneling Diode(RTD)that has both nonlinear and negative resistance characteristics is a semiconductor de-vice based on the quantum tunneling effect.Advantages of RTD include the facts that they can operate both as an oscillator and detector by changing the bias voltage and show advantages in the integration of communication and sensing for 6G.This paper introduces work-ing principles of RTD and the research progress of terahertz technology based on RTD from the aspects of terahertz sources,terahertz detectors,terahertz communication system and terahertz radar system,and discusses about current technological challenges and future perspectives.RTD-based terahertz technology will become an important development direction in the field of electronic devices in the future due to its outstanding advantages.
