    The initial growth stage of GaN growth directly on basal plane sapphire substrate is investigated. Statistical experimental design is used for the optimization of processes with a large number of interwoven effects. The effects of growth conditions on electrical and surface morphology are analyzed by means of Hall mobility and atomic force microscopy. The interactions between Ga flux and nitrogen power during the buffer growth are discussed.
