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

摘要

Semiconductor crystals are formed by applying a semiconductor 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) with metal having a sufficiently small area for crystal growth only from a single nucleus and having a greater nucleation density (NDL) than the nucleation density (NDS) of the deposition surface (SNDS) are arranged adjacent to each other, thereby growing a semiconductor single crystal from the single nucleus.
