Patent ID: 11522103

Abstract:
The present disclosure provides techniques for epitaxial oxide materials, structures and devices. In some embodiments, a semiconductor structure includes an epitaxial oxide heterostructure, comprising: a substrate; a first epitaxial oxide layer comprising (Nix1Mgy1Zn1−x1−yl)2GeO4 wherein 0≤x1≤1 and 0≤y1≤1; and a second epitaxial oxide layer comprising (Nix2Mgy2Zn1−x2−y2)2GeO4 wherein 0≤x2≤1 and 0≤y2≤1. In some cases, either: x1≠x2 and y1=y2; x1=x2 and y1≠y2; or x1≠x2 and y1≠y2. In some embodiments, a semiconductor structure includes an epitaxial oxide heterostructure, comprising: a substrate; a first epitaxial oxide layer comprising (Mgx1Zn1−x1)(Aly1Ga1−y1)2O4 wherein 0≤x1≤1 and 0≤y1≤1; and a second epitaxial oxide layer comprising (Nix2Mgy2Zn1−x2−y2)2GeO4 wherein 0≤x2≤1 and 0≤y2≤1.
