Figure 1

(a) Top and cross-sectional SEM images of the Pt layers electrodeposited at 0.2 V (vs. Ag/AgCl) in solutions containing 30 mM K2PtCl4 and 0.1 M H2SO4 with various deposition charge densities. Scale bar = 200 nm. (b) Dependence of the R f value and the thickness of the Pt layers on the deposition charge density. Each 5 data of the R f were used for error bar.
