Hierarchical ZnO nanostructures: Growth mechanisms and surface correlated photoluminescence

Mostrar todas las versiones(2)

ZnO nanowires were grown by vapor-transport and deposition on Au nanocluster covered fused and thermal silica and c-Si. The nanowire size and density depended strongly on the substrate type. By decreasing the O 2 to local Zn partial pressure ratio, the growth pattern changed to nanocombs and nanoshe...
