Effect of pulse width on deposition of diamond-like carbon on high power pulsed magnetron sputtering
Publikováno v:
Japanese Journal of Applied Physics.
A diamond-like carbon (DLC) film was deposited using high-power pulsed magnetron sputtering (HPPMS). The effect of pulse width on the deposition of DLC film was investigated under constant peak power density or average power density to clarify the de
