1. The growth of a crystalline layer on a crystalline substrate such that the layer has the same crystalline orientation as the substrate.
Usage: technical; materials science and semiconductor manufacturing

Examples

• Epitaxy is a key technique in the production of semiconductor devices.
• The silicon wafer underwent epitaxy to create a thin, perfectly aligned crystalline layer.
• Molecular beam epitaxy allows precise control over the growth of thin films.
• Engineers use epitaxy to manufacture high-quality integrated circuits.
• The epitaxy process ensures that the new crystal layer matches the atomic structure of the substrate.
