The compound semiconductors comprise a wide range of materials used in a variety of semiconductor devices and components. The compound semiconductors are unique in a way and therefore are used widely in power as well as opto-electronic devices and products demanding higher performance. They offer a variety of beneficial features including direct gap, wide range of band gaps, higher electron mobility, and low power consumption. Due to such unique properties, they find wide applications in Light Emitting Diodes (LEDs); high speed, high power devices; lasers, sensors, and IR-visible-UVs. The compound semiconductors have a wide scope in the fast developing world of science, technology, and applications. Therefore, the demand for compound semiconductor materials and related devices has been increasing in a drastic way, thereby, giving an exponential growth to the compound semiconductor industry.
