epitaxy
- noun
- /ˌɛpɪˈtæksi/
- Specialized
- Such islands can be produced by molecular-beam epitaxy and, within the constraints of the underlying lattice geometry, are distributed randomly on the surface in a variety of sizes and shapes.
- beam epitaxy
- molecular-beam epitaxy
- chemical-beam epitaxy

Surface Forms
Morphology
epitaxy = taxis (opaque) = epi + taxy
Formed from specialist combining forms (epi- + -taxy / taxis) used in technical contexts, so learners cannot reliably infer the meaning from the parts.
Etymology
Epitaxy comes from the parts epi- meaning 'upon' and taxis meaning 'order' or 'arrangement', the same root you see in tactic. Think of it like laying a thin sheet 'upon' a patterned floor so the sheet copies the pattern beneath it, which is why epitaxy means a crystal layer grows 'upon' another crystal and keeps the same order.
