InP Gunn Diodes with Current Limiting Contact for High Efficiency Gunn Oscillators

IEICE Transactions on Electronics, 2010
We fabricated and examined current limiting effect for InP Gunn diodes with stable depletion layer mode operation of diodes for high efficiency Gunn oscillators. Current limiting at the cathode was achieved by a shallow Schottky barrier at the interface.

An electrical equivalent circuit to simulate the output power of an AlGaAs/GaAs planar Gunn diode

, 2018
The planar Gunn diode offers the potential of microwave, milli-metric and THz based oscillator which can be fabricated as part of a microwave monolithic integrated circuit (mmic). To-date the RF output power has been too low for many applications.

Terahertz oscillations in an In_0.53Ga_0.47As submicron planar gunn diode [PDF]

, 2014
The length of the transit region of a Gunn diode determines the natural frequency at which it operates in fundamental mode – the shorter the device, the higher the frequency of operation. The long-held view on Gunn diode design is that for a functioning
