Characterization of bulk negative-resistance diode behavior

Abstract

Over certain ranges of frequency, bulk negative-resistance diodes can act as amplifiers or as oscillators depending on the doping, length between contacts, and external circuit. This behavior can be divided into four classes: Gunn oscillation, stable amplification, LSA oscillation, and bias-circuit oscillation. The four classes of behavior are discussed generally with references to the more detailed papers within this issue.
