Abstract(in Japanese) (See Japanese page)
Abstract(in English) GaN epitaxial layer grown on -c plane substrate by MOVPE has a smaller amount of carbon incorporation that compensates electrons than GaN on the + c plane substrate, making it possible to control lower impurity concentration in the drift layer of power device. Therefore, there is a possibility of realizing a high voltage device. However, there is a problem that the amount of oxygen incorporation is as high as 1018 cm-3 or more, therefore the depletion layer does not extend and the operating voltage becomes low. Therefore, in this research, we tried to grow at higher temperature to reduce oxygen concentration. As a result, reduction of luminescence caused by oxygen can be confirmed from PL measurement.
