Abstract

Graphene etching using oxygen neutral beam for high-quality graphene nanoribbon fabrication was investigated. A convenient index of D-band to G-band Raman intensity ratio showed that fewer defects on the edge of the graphene after neutral beam etching were observed than after plasma etching. The results demonstrate that damage-less graphene etching is possible by neutral beam etching due to suppression of UV photon radiation.
