Field emission characteristics of carbon nanocoils grown on copper micro-tips

摘要：

Carbon nanocoils(CNCs) were synthesized by using thennal chemical vapor deposition of C2H2 and NH3 gas at 600℃ over copper micro-tips formed on silicon substrate. Ctoppernikio-tips were formed by the high current pulse electroplating in order to investigate the effect of the surface morphology of the substrate on the growth of carbon nanostructures. We prepared three kinds of substrates with surface of electroplated copper micro-dps, electroplated copper film and evaporated copper film. Among the substrates, CNCs grown on the copper micro-tips showed the nicest field emission characteristics.
