Which diode operates on the principle that a high current, through a semiconductor material produces microwave oscillation? A. laser diode C. gun diode B. avalanche diode D. three-layer diode

Solution

Gunn Diode works on the principle that on providing High Frequency of current in a Semiconductor produces Microwave Oscillations. This diode is also called as a Transferred Electronic Device.

This diode is made up of a Single N type Semiconductor having the elements Galimum Arsenide.

When a high Voltage Current is applied,as the electrons from the conduction band having negligible electrical resistivity are transferred into the third band because these electrons are scattered by the applied voltage this result in increase in the forward voltage increases the field strength, thus producing Micro wave Oscillations.
