文摘
- •
Ultrafine Ag-coated Cu nanoparticles less than 20 nm in diameter were fabricated.
- •
Different Ag precursor concentrations influenced thickness and density of Ag shell.
- •
Excessive Ag precursor concentrations induced formation of surplus fine pure NPs.
- •
Ag dewetting behavior and Cu oxidation in Cu4@Ag1 nanoparticles were observed.
- •
Electrical resistivities of sintered Cu4@Ag1 films were 2.70–4.96 × 10−3 Ω cm.
