Potential graphene applications include lightweight, thin, and flexible electric/photonics circuits, solar cells, and various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials, and favoured by massive cost decreases in graphene production.

Graphene is the strongest material ever tested, [7] [8] with an intrinsic tensile strength of 130 GPa (19,000,000 psi) (with representative engineering tensile strength ~50-60 GPa for stretching large-area freestanding graphene) and a Young's modulus (stiffness) close to 1 TPa (150,000,000 psi).
The buffer layer does not exhibit the intrinsic electronic structure of graphene but induces considerable n-doping in the overlying monolayer graphene film. [17] [18] This is a source of electronic scattering and leads therefore to major problems for future electronic device applications based on SiC-supported graphene structures. [19]
Doped graphene layers have also shown the similar surface plasmon effects to that of metallic thin films. [7] [8] Through the engineering of metallic substrates or nanoparticles (e.g., gold, silver and copper) with graphene, the plasmonic properties of the hybrid structures could be tuned for improving the optoelectronic device performances.
The graphene spray gun would be utilized onto large-scale applications such as circuits, radio transmitters, and optical electronics due to its transparency and its high electrical conductivity. [2] The supersonic spray system was first developed in May 2014 by University of Illinois professor Alexander Yarin , and Korea University professor ...
A rapidly increasing list of graphene production techniques have been developed to enable graphene's use in commercial applications. [1]Isolated 2D crystals cannot be grown via chemical synthesis beyond small sizes even in principle, because the rapid growth of phonon density with increasing lateral size forces 2D crystallites to bend into the third dimension.

Scaling things down, graphene nanoribbons of less than 10 nm in width do exhibit electronic bandgaps and are therefore potential candidates for digital devices. Precise control over their dimensions, and hence electronic properties, however, represents a challenging goal, and the ribbons typically possess rough edges that are detrimental to ...
The electronic properties of graphene are significantly influenced by the supporting substrate. [59] [60] The Si(100)/H surface does not perturb graphene's electronic properties, whereas the interaction between it and the clean Si(100) surface changes its electronic states significantly. This effect results from the covalent bonding between C ...
