Resonant tunneling diodes for feeding antenna-structures for terahertz source applications

Caiyu Wang, Shubhendu Bhardwaj, John L. Volakis

Abstract

Resonant tunneling diodes (RTDs) have negative differential resistance (NDR) that enables them to produce power at several terahertz (THz). In this paper, an AlAs/GaAs/AlAs RTD is optimized for maximum output power and large negative differential resistance to improve matching to the antenna. Simulations for the designed RTD are based on the quantum-mechanical global coherent model.
