Fig. 5 Schematic growth process of ZnO nanorods with Au catalyst by high-pressure PLD a Au-Zn alloy particles formed by zinc atoms dissolved in gold droplets at high temperature; b The Au-Zn alloy is supersaturation due to absorption of ZnO precursor, and the quasi-hexagonal islands are formed with the precipitation of ZnO; c After transferring to the top of ZnO basement, the ZnO precursor is collected and grows into nanorod by screening effect; d ZnO nanorods grow quickly along 002 orientation, and the down of basement slowly growth into thin film
