| Outline of Final Research Achievements |
Structural and optical characterization were performed for thin m-plane AlInN epitaxial nanostructures grown by metalorganic vapor phase epitaxy. Crystal qualities of AlInN were remarkably improved via coherent growth on a low defect density m-plane freestanding GaN substrate prepared by hydride vapor phase epitaxy. All the epilayers unexceptionally suffer from uniaxial or biaxial anisotropic in-plane stress. However, full-width at half-maximum values of the x-ray x-rocking curves were nearly unchanged as the underlayer values being 80 ~ 150 arcsec. Applying the m-plane AlInN epitaxial nanostructures, planar vacuum fluorescent display devices emitting polarized DUV, blue, and green light were demonstrated.
