摘要：

The polytype conversion of a GaN film from N-face wurtzite to zinc-blende was investigated. The optical characteristics of GaN:Mg layers are very sensitive to the presence of the cubic polytype. Structural analysis by high-resolution transmission electron microscopy and high-resolution x-ray diffraction measurement revealed alignment of the cubic phase with the [111] axis perpendicular to the substrate surface. A cubic-related donor-acceptor transition at ∼3.16 eV is also observed, together with a broad blue band around 2.9 eV.
