For Gunn Diode Semiconductor Material Preferred Is?

For gunn diodes semiconductor material preferred is ga as n-type semiconductor. The most common materials are gallium Arsenide, GaAs and Indium Phosphide, InP. However other materials including Ge, CdTe, InAs, InSb, ZnSe and others have been used.

Which semiconductor is used in Gunn diode?

Gunn Diode's Working

This diode is made of a single piece of N-type semiconductor such as Gallium Arsenide and InP (Indium Phosphide). GaAs and some other semiconductor materials have one extra-energy band in their electronic band structure instead of having only two energy bands, viz.

Why GaAs is used in Gunn diode?

Explanation: a gunn diode is a bulk device, that is, it does not contain any junction but it is a slice of n-type gaas. p- type gaas does not exhibit gunn effect. hence it is a reversible and can be operated in both directions.
