ZnO-Kristall, sein Aufwuchsverfahren und ein Herstellungsverfahren für eine Leuchtvorrichtung

摘要

A ZnO crystal growth method has the steps of (a) preparing a substrate having a surface capable of growing ZnO crystal exposing a Zn polarity plane; (b) supplying Zn and O above the surface of the substrate by alternately repeating a Zn-rich condition period and an O-rich condition period; and (c) supplying conductivity type determining impurities above the surface of the substrate while Zn and O are supplied at the step (b).
