Systematic control of the size, density and configuration of Pt nanostructures on sapphire (0Â 0Â 0Â 1) by the variation of deposition amount and dwelling time

- The evolution of size, density and configuration of Pt nanostructures was successfully demonstrated on sapphire (0 0 0 1).
- Influence of synthesis parameters such as deposition amount and dwelling time were systematically investigated in depth.
- Four distinctive configuration and evolution of Pt nanostructures was observed with the systematic control of growth parameters.
