Epitaxy, the process of growing a crystal of a particular orientation on top of another crystal, where the orientation is determined by the underlying crystal. The creation of various layers in semiconductor wafers, such as those used in integrated circuits, is a typical application for the addition, epitaxy is often used to fabricate optoelectronic devices.

What are compound semiconductors for. Since electrons in compound semiconductors move much faster than electrons in silicon, the most popular single-element semiconductor, compound semiconductors are ideal for high-speed signal processing.
