Abstract

Diamond-like Carbon (DLC) films were deposited on nickel sheets and tungsten tips by liquid-phase electrodeposition, and were investigated by using field emission scanning electron microscopy (FE-SEM), Raman spectroscopy and atom probe (AP). The surface morphology of the deposited films was observed by FE-SEM. It can be seen that the films were composed of small grains. Raman spectra of the films exhibited two broad peaks around 1200-1450 cm-1 called D-peak and 1500-1700 cm-1 called G-peak. By AP analysis, some hydrocarbon ions were detected. It indicates that the films were composed by not only carbon but also hydrogen.
