To form several-micrometer-thick diamond-like carbon (DLC) films, pulse bias filtered cathodic vacuum arc deposition was performed, In this study, nonhydrogenated DLC films were evaluated using visible and ultraviolet Raman spectroscopy, an electron energy loss spectroscopy (EELS) and a nano indenter. All observations indicated that the sp3 ratio of the DLC films decreases with increasing applied pulse bias. However, a moderately high sp 3 ratio of 42.3% was obtained for 500-nm-thick PLC films with a compressive stress of 3.5 GPa formed at a pulse bias of 500 V, a pulse width of 25 μs, and a frequency of 1500Hz.
