InGaAs/InP epi wafer for PIN

InGaAs is the compound of InAs and GaAs. In the periodic table of chemical elements, In and Ga are elements of the third group, and As is the fifth group element. The properties of InGaAs are between the properties of GaAs and inAs. As a room temperature semiconductor, InGaAs is widely used in electronics and photonics nowadays.
