| Outline of Final Research Achievements |
The target of this project is for fabricating GaN growth on Al templates, which can be separated from the sapphire substrate using chemical liftoff techniques, and near UV transparent conductive films for GaN-based integrated surface emitting devices. The detailed research topics are the followings; (1) the fabrication of GaN layers grown on Al templates, and (2) the realization of GaN-based integrated surface emitting devices with transparent conductive films fabricated by molecular precursor method. In the topic 1, we grew GaN films on pseudo Al substrates by molecular beam epitaxy (MBE) and investigated the growth mechanisms on the pseudo substrates. The surface cracks can be reduced using a low-temperature buffer deposition. In the topic 2, we fabricated GaInOx thin films by molecular precursor method, which is one of the solution techniques using spin coating. These films were also fabricated on a blue LED structure.
