etched in graphene encapsulated by hexagonal boron nitride, which results in profound effects on the band structure and the resulting quantum transport [1]. Through the high-quality lithographic patterning of the graphene, we achieve ballistic transport while opening a bandgap on the order of 0.15 eV. In magnetotransport

Materials with this single layer structure are often referred to as 2D materials. Multiple layers of graphene stacked on topofeachotherformgraphite. These 2D materials are an interesting area of study because they have some unusual physical properties. Band-structure topologies of graphene: Spin-orbit coupling effects from first principles M. Gmitra, 1S. Konschuh, C. Ertler, C. Ambrosch-Draxl,2 and J. Fabian1 1Institute for Theoretical Physics, University of Regensburg, 93040 Regensburg, Germany 2019-05-08 · A three-dimensional band structure plot, depicted in figure 2(a), reveals the bands intersecting the Fermi level under the R-45° supercell of T graphene. Two bands intersect with each other and form a corresponding 'node circle' on the Fermi surface (a continuous Dirac points at the Fermi level), as presented in figure 2(b). The electronic band structure of graphene in the presence of spin-orbit coupling and transverse electric field is investigated from first principles using the linearized augmented plane-wave method.

We describe the synthesis of bilayer graphene thin films deposited on insulating silicon carbide and report the characterization of their electronic band structure using angle-resolved photoemission. By selectively adjusting the carrier concentration in each layer, changes in the Coulomb potential led to control of the gap between valence and conduction bands. This control over the band

1-7 Article in journal (Refereed) Published Abstract [en] Studies of the effects induced on the electron band structure after Na deposition, and subsequent heating, on a C-face 2 MLs graphene sample are reported. We describe the synthesis of bilayer graphene thin films deposited on insulating silicon carbide and report the characterization of their electronic band structure using angle-resolved photoemission. By selectively adjusting the carrier concentration in each layer, changes in the Coulomb potential led to control of the gap between valence and conduction bands.
