ALD synthesis of platinum nanoparticles on single-crystal SrTiO3 pretreated with wet chemical etching
چکیده انگلیسی
Formic acid-hydrogen peroxide and buffered hydrogen fluoride-hydrogen peroxide solutions were used to etch single-crystal strontium titanate to remove carbon contamination and increase hydroxyl group density to improve atomic layer deposition onto these materials. X-ray photoelectron spectroscopy indicated that both are effective for carbon contamination removal. However, for increasing hydroxyl group density on the strontium titanate surface, the buffered hydrogen fluoride-hydrogen peroxide is more effective. Transmission electron microscopy and x-ray photoemission show enhanced platinum deposition on the etched strontium titanate surface. These results provide the basis for optimizing atomic layer deposition for other technologically relevant materials.
