Notes:
We developed a new zinc oxide (ZnO) crystal growth method using Au combined withelectric current heating. Au paste was placed on a ZnO ceramic bar. When a certain current flowedthrough the bar, the paste melted on the bar. Then crystals grew on the molten Au surface immediately.The shape of the crystals depended on the atmosphere during the growth. The whiskers with sphericaltop and the crystals consisting of a hexangular pyramidal base and needle head were grown on Au inair and Ar atmosphere, respectively. From cathodoluminescence at room temperature, the weakultraviolet (UV) emission at approximately 3.2 eV and the strong visible emission at approximately2.3 eV were observed from the whisker grown in air. The UV emission at approximately 3.3 eVdominated a spectrum from the pyramidal crystal grown in Ar atmosphere
