Meaning and Definition
A high-frequency oscillation in the current flowing through certain semiconductors when a strong electric field is applied, discovered by physicist J. B. Gunn.
The physical phenomenon where a semiconductor like gallium arsenide exhibits a negative differential resistance region, resulting in spontaneous current oscillations that can be used to generate microwave frequencies.

FAQ
Frequently Asked Questions
Indirectly, yes. Devices based on it (Gunn diodes) are used in motion detectors, radar speed guns, and microwave communication systems, but the term itself is not used casually.
It was discovered by physicist J. B. Gunn at IBM in 1963.
No, it is primarily observed in compound semiconductors like gallium arsenide (GaAs) and indium phosphide (InP).
Its main application is in the creation of Gunn diodes, which are simple, solid-state sources of microwave radio waves.
