چکیده

Abstract Theoretical investigation of thermodynamic properties of electrically modulated monolayer graphene in the presence of a perpendicular magnetic field B is presented. The results obtained are compared with those of the conventional 2DEG. The one-dimentional periodic potential due to electric modulation lifts the degeneracy of the Landau Levels and converts them into bands whose width oscillates as the function of B. We find Weiss type oscillations for small values of B and dHvA type oscillations at larger values values of B. These oscillations are more pronounced in Graphene than in conventional 2DEG system. These oscillations are less damped with temperature in Graphene compared with conventional 2DEG systems.

Temperature effects on the magnetoplasmon spectrum of a weakly modulated graphene monolayer.

In this work, we determine the effects of temperature on the magnetoplasmon spectrum of an electrically modulated graphene monolayer as well as a two-dimensional electron gas (2DEG). The intra-Landau band magnetoplasmon spectrum within the self-consistent field approach is investigated for both the aforementioned systems. Results obtained not only exhibit Shubnikov-de Haas (SdH) oscillations bu...
