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

Laser induced white lighting of graphene foam [PDF]

Scientific Reports, 2017
AbstractLaser induced white light emission was observed from porous graphene foam irradiated with a focused continuous wave beam of the infrared laser diode. It was found that the intensity of the emission increases exponentially with increasing laser power density, having a saturation level at ca.

Raman spectra of bilayer graphene covered with Poly(methyl methacrylate) thin film

AIP Advances, 2012
The Raman spectra of bilayer graphene covered with poly(methyl methacrylate) (PMMA) were investigated. Both the G and 2D peaks of PMMA-coated graphene were stiff and broad compared with those of uncovered graphene.

Laser-induced graphene on cross-linked sodium alginate [PDF]

Nanotechnology, 2023
Abstract Laser-induced graphene (LIG) possesses desirable properties for numerous applications. However, LIG formation on biocompatible substrates is needed to further augment the integration of LIG-based technologies into nanobiotechnology. Here, LIG formation on cross-linked sodium alginate is reported.

Weak mismatch epitaxy and structural feedback in graphene growth on copper foil [PDF]

, 2013
Graphene growth by low-pressure chemical vapor deposition on low cost copper foils shows great promise for large scale applications. It is known that the local crystallography of the foil influences the graphene growth rate.
