Relating to a method of growing a crystalline layer on a substrate in a specific orientation.
The researchers used an epitaxial process to create high-quality semiconductor materials.
Epitaxial → It is formed from "epi-" (meaning upon or over) and "taxis" (from Greek "taxis", meaning arrangement or order). The term epitaxial refers to the arrangement of a crystalline layer on a substrate, indicating a specific orientation or order upon another layer.
Think of 'epi-' meaning 'upon' and 'taxis' meaning 'arrangement' — this helps you remember that epitaxial refers to a specific arrangement of layers.
