Indium Phosphide 

Indium phosphide (InP) and its related compounds with Aluminium, Arsenide and Gallium forms the basis of many of the devices enabling the revolution in communication. InP is used in high-power and
high-frequency optoelectronics and electronics such as solid state lasers. Its superior electron velocity and direct bandgap result in fast switching optical components able to transmit huge amounts of data quickly. It can be etched using Inductively Coupled Plasma (ICP), Reactive Ion Etching (RIE) or Ion Beam Etch (IBE).
