Liquid phase deposition of hydrogenated diamond-like carbon films on conductive glass substrates using a pulse-modulated source

Hydrogenated diamond-like carbon films about 300-500 nm thick were deposited on conductive glass substrates by the electrolysis of a methanol solution, using a pulse-modulated source. The structures of the films were analyzed by XPS, Raman, and IR spectroscopy. The electrical resistivity of the films was in the 10¹⁰ Ω cm range, leading to a remarkable decrease in the current density of the substrates at the initial stage of deposition.
