Abstract
The present invention provides a method for preparing a thin or thick film, comprising the steps of: (1) arranging non-spherical seed crystals on a substrate such that all the a-, b- and c-axes of each seed crystal are oriented under a predetermined rule; and (2) forming and growing the film from the seed crystals through secondary growth by exposing the arranged seed crystals of step (1) to a seed crystal growth solution. The invention also provides a film prepared by the method. According to the invention, crystals or films larger than the seed crystals can be prepared.
