By using the Au-catalyzed vapor-liquid-solid growth of ZnO and In2O3 nanowires as examples,we demonstrate the critical role of the coalescence of Au catalyst nanoparticles in determining the final diameter distribution of oxide nanowires. The enhanced coalescence is facilitated by a transient liquid...
