[ad. F. épitaxie (L. Royer 1928, in Bull. de la Soc. française de Min. LI. 8), f. epi- + Gr. τάξις arrangement: see -y3.]
The growth of crystals on a crystalline substrate that determines their orientation; the orientation of crystals so grown.

V. 495 For epitaxy there is required both geometrical agreement and similarity of polarity between particles which replace one another at the points of union. 1949Proc. Physical Soc.

Hence epiˈtaxial a. [-al], grown by, characterized by, or resulting from epitaxy: used of crystals, crystal growth, and crystal orientation; epiˈtaxially adv., so that epitaxy occurs; by an epitaxial process.
