In this study, in order to solve the fluctuation of the light emitting wave length and color rendering properties, the selective area growth on a plane GaN and the fabrication of the flat m-plane GaN are carried out aiming at the development of the white LED with continuous and wide wavelength range. By controlling growth temperature and growth pressure, the facet controlled structures can be fabricated. Also by using this technique, the flat m-plane GaN can be obtained. From these results, The development of the white LED with continuous and wide wavelength range can be realized.
