Dynamic elastance of a Gunn diode
The time-varying elastance of a Gunn diode is deduced by the application of a simple domain-growth and decay model. The time variation of the elastance is seen to be significantly different from the previously assumed ideal pulsed nature.

Gunn diode modelling through a new load-pull characterization method [PDF]
This paper presents a very efficient Gunn diode circuit model whose components are determined by a new method of large signal characterization which requires much less power from the generator than classical techniques.

InP Gunn diodes with a cathode contact injecting hot electrons. Part 1. Interactions between phases in the cathode contacts [PDF]
The article presents the research on interactions between phases in the Ge–Au, Ge–TiBx and Au–TiBxAu contacts to n–n+–n++-InP, both before and after rapid thermal annealing, and also the output parameters of Gunn diodes based on the InP structure with Au–

Gunn diodes from GaAs with the cathode contact by injecting hot electrons
Gunn diodes made of GaAs with a cathode contact AuGe–TiB2–Au that injects hot electrons have been developed. The Gunn diodes operate in the frequency range from 17.44 to 78.0 GHz with efficiencies from 8% to 4%, respectively.

X band Gunn oscillators triggered by baseband Gunn diodes
A 155 μm-long Gunn diode produces output pulses of 1.5 V amplitude in resistive loading. These pulses are used to trigger a transistor multivibrator and an X band Gunn oscillator.
