Patent ID: 8921851

Claim:
A method for growing a non-polar (13 4 0) plane epitaxy layer of wurtzite structure, which comprises the following steps: providing a single crystal oxide with perovskite structure; selecting a plane of the single crystal oxide as a substrate; and forming a non-polar (13 4 0) plane epitaxy layer of wurtzite semiconductors on the plane of the substrate by a vapor deposition process; wherein the single crystal oxide is an oxide with perovskite structure of LaAlO 3 , LaNiO 3 , LaGaO 3 , SrTiO 3 , (LaSr)(AlTa)O 3 , PrAlO 3 , or NdAlO 3 ; wherein the non-polar (13 4 0) plane epitaxy layer is a zinc oxide, or a Group III nitride: wherein the zinc oxide is further doped with magnesium, calcium, strontium, barium, cadmium, aluminum, gallium, indium, or combinations thereof.
