Making Graphene Luminescent by Oxygen Plasma Treatment [PDF]

, 2009
We show that strong photoluminescence (PL) can be induced in single-layer graphene using an oxygen plasma treatment. The PL is spatially uniform across the flakes and connected to elastic scattering spectra distinctly different from those of gapless ...

Fabrication and ab initio study of downscaled graphene nanoelectronic devices [PDF]

, 2012
In this paper we first present a new fabrication process of downscaled graphene nanodevices based on direct milling of graphene using an atomic-size helium ion beam. We address the issue of contamination caused by the electron-beam lithography process to
