NATURAL SUPERLATTICE HOMOLOGOUS SINGLE CRYSTAL THIN FILM, METHOD FOR PREPARATION THEREOF, AND DEVICE USING SAID SINGLE CRYSTAL THIN FILM

摘要

Disclosed is a natural-superlattice homologous single-crystal thin film, which comprises a complex oxide which is epitaxially grown on either one of a ZnO epitaxial thin film formed on a single-crystal substrate, the single-crystal substrate after disappearance of the ZnO epitaxial thin film and a ZnO single crystal. The complex oxide is expressed by the formula: M<1>M<2>O3 (ZnO)m, wherein M<1> is at least one selected from the group consisting of Ga, Fe, Sc, In, Lu, Yb, Tm, Er, Ho and Y, M<2> is at least one selected from the group consisting of Mn, Fe, Ga, In and Al, and m is a natural number of 1 or more. A natural-superlattice homologous single-crystal thin film formed by depositing the complex oxide and subjecting the obtained layered film to a thermal anneal treatment can be used in optimal devices, electronic devices and X-ray optical devices.
