Indium Phosphide (InP) is an important III-V compound and semiconductor material with advantages of high electron mobility, good radiation stability, and large band gap. It has a face-centered cubic ("zincblende") crystal structure, identical to that of GaAs and most of the III-V semiconductors. With stable physical and chemical properties, InP is widely used in optical fiber communication, microwave, millimeter wave(MMV), radiation-resistant solar cells and other fields. InP is also used as a substrate for epitaxial indium gallium arsenide based opto-electronic devices.
Indium Phosphide (InP) is also used in high-power and high-frequency electronics (High-electron-mobility transistor, Heterojunction bipolar transistor) because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide. It was used with indium gallium arsenide to make a record breaking pseudomorphic heterojunction bipolar transistors that could operate at 604 GHz. Also today’s state-of-the-art high-efficiency solar cells for concentrator photovoltaics (CPV) and for space applications use (Ga)InP and other III-V compounds to achieve the required bandgap combinations.
Indium Phosphide has particular advantage in two applications:
Photonics : Emission and detection capacities with more than 1,000nm wave length.
RF: High-speed and low noise performance in high frequency RF applications. InP is the first choice for performance-driven niche markets in communication, radar, test equipment, and radiation measurement.
