Abstract :

Due to the high aspect ratio and stable mechanical properties, the conical surface nanostructures show wide potentials in many application fields such as optics, electronics, thermology and biology. In this work, we developed a bias-assisted plasma etching technology for fabricating diamond nanocone arrays. The as-formed diamond nanocone arrays show many advantages such as large area, uniform orientation and controllable density. We suggested that the self-organized selective sputtering effect of methylic ions play key roles for the formation of nanocones. The field electron emission, electron transport properties and other physical properties from the diamond and graphene/diamond nanocones are studied.
