摘要: Au nanoparticles (NPs) have been utilized in a wide range of device applications as well catalysts for the fabrication nanopores and nanowires, which performance associated devices morphology nanowires are strongly dependent on size, density, configuration NPs. In this paper, evolution self-assembled nanostructures NPs sapphire (0001) is systematically investigated with variation annealing temperature (AT) dwelling time (DT). At low-temperature between 300 600 °C, three distinct regimes nanostructure observed, i.e., vermiform-like piles, irregular nano-mounds, islands. Subsequently, being provided relatively high thermal energy 700 900 °C, round dome-shaped fabricated based Volmer-Weber growth model. With increased AT, size gradually due to more favorable surface diffusion while density decreased compensation. On other hand, DT, decrease evaporation at 950 °C.
