Chemistry Makes Graphene beyond Graphene

Journal of the American Chemical Society, 2014
Although graphene is extremely inert in chemistry because of the giant delocalized π electron system, various methods have been developed to achieve its efficient chemical modification. Covalent chemistry is effective to modulate the physical properties of graphene. By converting the sp(2) hybridized carbon atoms to sp(3) ones, new two-dimensional (2D)

Bilayer graphene by bonding CVD graphene to epitaxial graphene

Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2012
A novel method for creating bilayer graphene is described where single-layer CVD graphene grown on Cu is bonded to single-layer epitaxial graphene grown on Si-face SiC. Raman microscopy and x ray photoelectron spectroscopy demonstrate the uniqueness of this bilayer, as compared to a naturally formed bilayer, in that a Bernal stack is not formed with ...

The structure of suspended graphene sheets

Nature, 2007
The recent discovery of graphene has sparked much interest, thus far focused on the peculiar electronic structure of this material, in which charge carriers mimic massless relativistic particles. However, the physical structure of graphene—a single layer

Patterning of graphene

Nanoscale, 2012
Two-dimensional atomic sheets of carbon (graphene, graphane, etc.) are amenable to unique patterning schemes such as cutting, bending, folding and fusion that are predicted to lead to interesting properties. In this review, we present theoretical understanding and processing routes for patterning graphene and highlight potential applications. With more

Graphene Nanoribbons and Doped Graphene

2023
Graphene has been an interesting material for scientists and engineers by virtue of its remarkable properties. It has unique electronic properties with zero bandgap at the Dirac point. The absence of bandgap in graphene limits its application in electronics.
