Evolution of self-assembled Au droplets induced by variation of annealing temperature: from 50°C to 350°C. Au droplets are fabricated with a fixed deposition amount of 2 nm and a fixed annealing duration of 30 s at each annealing temperature. (a) to (d) are AFM top views and (a-1) to (d-1) show AFM side views of 1 × 1 μm2.
