Abstract

The thermal stability of Gd2O3 films as a function of incorporated ZrO2 was investigated. The structural characteristics of epitaxial Gd2O3 with the codeposition of Zn were maintained on the Si(111) substrate. The improved cyrstallinity of the film and suppressed interfacial reactions were observed by the incorporation of ZrO2 in Gd2O3. Depending on the microstructural changes, the structutral stability in the epitaxial structure with no deformation was enhanced upto 800°C. The extensive interactions between Gd and Si which caused interfacial defects were also minimized.
