Method for forming crystal and crystal article obtained by said method.

摘要

A method for forming a crystal, which comprises applying a crystal forming treatment on a substrate having a free surface on which a deposition surface (SNDS) with a small nucleation density and a deposition surface (SNDL) having a sufficinetly small area for crystal growth only from a single nucleus and having a greater nucleation density (NDL) than the nucleation density (NDS) of said deposition surface (SNDS) are arranged adjacent to each other, thereby growing a single crystal from said single nucleus.
