Thermodynamic Properties of electrically modulated monolayer Graphene
Abstract Theoretical investigation of thermodynamic properties of electrically modulated monolayer graphene in the presence of a perpendicular magnetic field B is presented. This work is aimed at determining the modulation induced effects on the thermodynamic properties of electrically modulated graphene.The results obtained are compared with those of the conventional 2DEG. The one-dimensional ...
متن کاملThermodynamic Properties of electrically modulated monolayer Graphene: Theory
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 osc...
متن کاملRandom-gap model for graphene and graphene bilayers.
The effect of a randomly fluctuating gap, created by a random staggered potential, is studied in a monolayer and a bilayer of graphene. The density of states, the one-particle scattering rate, and the transport properties (diffusion coefficient and conductivity) are calculated at the neutrality point. All of these quantities vanish at a critical value of the average staggered potential, signali...
متن کاملDefluoridation of Aqueous Solution by Graphene and Graphene Oxide Nanoparticles: Thermodynamic and Isotherm Studies
Fluoride, a non-essential element, can enter water resources through several natural processes and human activities. The benefits and risks of fluoride depend on the concentration of this anion on drinking waters. In the present study, the performances of graphene and graphene oxide nanoparticles were investigated for the removal of fluoride from aqueous solution. In the present resea...
متن کاملMonovacancy-induced magnetism in graphene bilayers.
Vacancy-induced magnetism in graphene bilayers is investigated using spin-polarized density functional theory calculations. One of two graphene layers has a monovacancy. Two atomic configurations for bilayers are considered with respect to the position of the monovacancy. We find that spin magnetic moments localized at the vacancy site decrease by ∼10% for our two configurations, compared with ...
