We invistegated the characteristic of GaN grown on LiAlO2 substrate by molecular epitaxy beam. We observed the c-plane GaN crystalls assembled at the step-edge of M-plane GaN terraces, with 200 nm ~ 600 nm diameter and 300 nm height. Furthermore, we also observed that there are two kinds of formations for c-palne GaN: one is grown from the hexagonal plane of LAO, the other is transformed from the defeat of M-plane GaN. In addition, we changed the growth ratio and concluded some relation between the quality of thin film and roughness of surface. We expect to improve the quality of M-plane GaN and the size and density of c-plane GaN single-crystals by changing growth conditions.
