Mg-CONTAINING ZnO MIXED SINGLE CRYSTAL, LAMINATE THEREOF AND THEIR PRODUCTION METHODS

摘要

The present invention can provide an Mg-containing ZnO mixed single crystal
wherein the mixed single crystal comprises an Mg-containing ZnO semiconductor having a bandgap (Eg) of 3.30 < Eg ‰¤ 3.54 eV, and has a film thickness of 5 µm or less. The present invention can provide a method for producing an Mg-containing ZnO mixed single crystal by liquid phase epitaxial growth, wherein the method comprises: mixing and melting ZnO and MgO as solutes and PbO and Bi 2 O 3 (or PbF 2 and PbO) as solvents; and putting a substrate into direct contact with the obtained melt solution, thereby growing the Mg-containing ZnO mixed single crystal on the substrate.
