摘要
Nonpolar m-plane GaN films have been grown by metalorganic vapor-phase epitaxy on patterned a-plane sapphire substrates (diameter: 3 in.) without dielectric masks made of materials such as SiO(2). The m-plane GaN layer had a smooth and transparent surface over the entire area of the substrate. Furthermore, the epitaxial relationships between the m-plane GaN film and the patterned a-plane sapphire substrate were as follows: [0001](GaN) parallel to [0001](Sapphire) and [11 (2) over bar0](GaN) parallel to [10 (1) over bar0](Sapphire). The full width at half maximum values of the X-ray rocking curves for (10 (1) over bar0) GaN along [11 (2) over bar0](GaN) and [0001](GaN) were found to be 396 and 565 arcsec, respectively.
