| Abstract(in English) | ZnO has been regarded as an ideal substrate for epitaxial growth of nonpolar group III nitride films because its structural properties are quite similar to those of GaN. However, ZnO has not been used as the substrate due to its chemical instability under the conventional growth conditions of metal-organic vapor phase epitaxy. We have recently found that the use of "pulsed-laser-deposition room-temperature growth technique" enables us to fabricate abrupt nonplolar interfaces, and to solve the instability of ZnO. In this paper, we report that there exist anisotropic in-plane strains in m-plane InGaN films grown on ZnO substrates, which influence the optical polarization properties. |
