We investigated the dynamics of zinc (Zn) and oxygen (O) adsorbed atoms (adatoms) on a Zn-polar ZnO(0001) surface using the first-principles calculation. The results of the first-principles calculation revealed that a high-quality ZnO crystalline growth condition is induced by wurtzite structure packing under a Zn-rich growth condition using a Zn-polar ZnO(0001) surface. However, it was shown that an O adatom is not sufficient to promote surface atomic diffusion. For high-quality ZnO crystal, promoting surface diffusion of adatoms using high temperature is important.
