Carbon nanowalls grown by microwave plasma enhanced chemical vapor deposition

Abstract

Nanowalls, a new nanostructural morphology of carbon, grow instead of nanotubes under microwave plasma-enhanced CVD conditions on substrates electrically disconnected from the lower electrode. While not fully understood, the formation of nanowalls appears to depend on the local electric field. Due to their large surface, nanotubes may find applications in field emission displays and energy storage devices.
