A ZnS thin film was electrodeposited on the surface of nanopores of porous silicon (PSi) without plugging of the nanopores. And the optical properties of the ZnS/PSi composites were investigated. The PSi was fabricated by anodization of n-Si (100) wafer in HF/EtOH/H2O solution under constant current conditions. The pore diameter and the porous layer depth of the PSi were 20–80nm and 8–50μm, respectively,...
TiO2/porous Si (PSi) nanocomposites were fabricated by liquid-phase deposition with anodization of PSi. Scanning electron microscopy-energy-dispersive X-ray spectroscopy showed that TiO2 was only deposited in the fine pores of anodized PSi (ca. 7.4nm) when the PSi surface was anodized in the presence of Ti ions as F− scavengers. The TiO2/PSi nanocomposites were fabricated by anodization of PSi in...
