Gunn effect (g n)n. The production of microwave oscillations when a constant voltage in excess of a critical level is applied to opposite faces of a semiconductor. [After John Battiscombe Gunn (born 1928), Egyptian-born British physicist.] |
Gunn effect [gʌn]
n
(Physics / General Physics) a phenomenon observed in some semiconductors in which a steady electric field of magnitude greater than a threshold value generates electrical oscillations with microwave frequencies
[named after John Battiscombe Gunn (born 1928), British physicist]
