Abstract
Highly oriented thin film In2O3 was heteroepitaxially grown on an optically polished (001) plane of single crystalline yttria stabilized zirconia (YSZ) substrate using molecular beam epitaxy (MBE). The full-width at half maximum (FWHM) of the X-ray rocking curve was 0.08° for 200-nm-thick In2O3 layers indicating excellent uniformity of the crystallographic orientation compared with the heteroepitaxially-grown In2O3 deposited by a conventional method such as electron-beam (e-beam) evaporation. The minimum yield (χmin ) of the MBE grown In2O3 film obtained from Rutherford backscattering (RBS) spectra was also extremely small with a value of 3.1% implying high crystallinity with very low lattice defect density.Keywords
