Epitaxial growth

What is the origin of the word "epitaxy"?

  1. AGreek "epi" (upon) and "taxis" (arrangement)
  2. BLatin "epi" (heat) and "taxis" (melt)
  3. CThe inventor's name
Show answer and explanation

Answer: A. Greek "epi" (upon) and "taxis" (arrangement)

Epitaxy combines the Greek "epi" (upon) and "taxis" (arrangement), describing the growth of crystal on top of a substrate crystal, aligned with its arrangement.

  • A. Correct. It means "arranged upon".
  • B. It does not mean heat or melting.
  • C. It does not come from a person's name.
