Journal ArticleDOI
The electronic properties of graphene
TL;DR: In this paper, the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations, are discussed.
Journal ArticleDOI
2D materials and van der Waals heterostructures
TL;DR: Two-dimensional heterostructures with extended range of functionalities yields a range of possible applications, and spectrum reconstruction in graphene interacting with hBN allowed several groups to study the Hofstadter butterfly effect and topological currents in such a system.
Journal ArticleDOI
Strong light-matter interactions in heterostructures of atomically thin films.

TL;DR: Transition metal dichalcogenides sandwiched between two layers of graphene produce an enhanced photoresponse, which allows development of extremely efficient flexible photovoltaic devices with photoresponsivity above 0.1 ampere per watt (corresponding to an external quantum efficiency of above 30%).
Journal ArticleDOI
Substrate-induced bandgap opening in epitaxial graphene
Shuyun Zhou,Gey-Hong Gweon,Gey-Hong Gweon,Alexei V. Fedorov,Phillip N. First,W. A. de Heer,D.-H. Lee,Francisco Guinea,A. H. Castro Neto,Alessandra Lanzara,Alessandra Lanzara +10 more
TL;DR: It is shown that when graphene is epitaxially grown on SiC substrate, a gap of approximately 0.26 eV is produced and it is proposed that the origin of this gap is the breaking of sublattice symmetry owing to the graphene-substrate interaction.
Journal ArticleDOI
Making graphene visible
Peter Blake,Ernie W. Hill,A. H. Castro Neto,K. S. Novoselov,Da Jiang,R. Yang,Timothy J. Booth,A. K. Geim +7 more
TL;DR: In this article, the authors study the visibility of graphene and show that it depends strongly on both thickness of SiO2 and light wavelength, and they find that ≈100nm is the most suitable wavelength for its visual detection.
