Preferred crystal orientation
WebApr 1, 2009 · The development of a preferred crystal orientation during growth is called geometric selection. A theory of geometric selection in two-dimensions for infinitely thin needles growing on a half-plane was brought forward by Kolmogorov (1949).He predicts that the number of crystals N(z) at the one-dimensional interface of length l at depth z is given … WebAug 1, 2024 · The [001] crystal orientation of anatase crystal nuclei was uniform parallel to the normal direction of TiO 2 film growth surface. During the annealing process, the nano-size anatase crystal nuclei grew and coalesced into the large anatase grains without the change of [001] crystal orientation, which resulted in TiO 2 film with obvious (001) …
