Abstract
Without catalysis, hexagonal zinc oxide (ZnO) microcrystals were successfully grown on (0001) sapphire substrate in a home made chemical vapor deposition system under atmospheric pressure. A rapid lateral growth at rate of 15μm/h and a dense growth of ZnO crystals were realized in the growth regions of 800 and 850°C, respectively. The growth mechanisms were explained similarly with the selective epitaxy. The high quality of the crystals was attested by the X-ray diffraction pattern, Raman scattering and temperature dependent photoluminescence. These results showed the potential of lateral growth ZnO crystals at low cost.
