Structures and Physics of Resonant Tunneling Diodes for Terahertz Oscillators

Abstract

Resonant tunneling diode (RTD) is one candidate for compact and coherent room-temperature terahertz sources. In this paper, we introduce our recent results on RTD terahertz oscillators, including RTD materials and structures for high frequency oscillation. Up to now, oscillation at 1.98 THz has been achieved at room temperature. We also described structures for high output power and some applications of RTD oscillators.
