What is a Compound Semiconductor?

Apart from silicon, there are compound semiconductors that combine Group III and V elements and Group II and VI elements. For example, GaAs, InP, InGaAlP, etc. have been conventionally used for high-frequency devices and optical devices.
In recent years, InGaN has been attracting attention as a material for blue LEDs and laser diodes, and SiC and GaN as materials for power semiconductors have been noted and commercialized.

Typical compound semiconductors
Group II-VI: ZnSe
Group III-V: GaAs, GaN, InP, InGaAlP, InGaN
Group IV-IV: SiC, SiGe
