Abstract:Diamond-like carbon (DLC) films were electrodeposited on aluminum from acetonitrile with a pulse-modulated power at room temperature. The films were grey with 1 7m in thickness. The resistivity of the films was of the order of 107 Q cm The films were characterized by X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. XPS shows that the main composition of the films is carbon. Raman spectra indicate that typical DLC films were formed when high potential (>800 V) was applied.
