Cross-sectional SEI of microporous silicon after the electrodeposition of platinum and silver. After the electrodeposition of platinum and silver. Images of (a) and (b) are the cross-sections of platinum deposition in 0.1 M K2PtCl4 + 0.5 M NaCl, and those of (c) and (d) are case of silver deposition in 0.1 M AgNO3 + 0.5 M KNO3. The images in (a, c) and (b, d) show the samples of the hydrophilic and hydrophobic microporous silicon, respectively.
