DLC Thin Film Assisted ZnO Nanowires Growth

In this study, we successfully fabricated dense, uniform, vertically aligned ZnO NWs on top of DLC films. The NWs’ length, diameter and separation distance were controllable by fine tuning the growth parameters and changing the DLC film deposition temperature…
