Thermodynamic properties of graphene nanoribbons under zero and quantizing magnetic fields

Journal Article


Abstract


  • The thermodynamic properties of graphene nanoribbons under zero and finite magnetic fields have

    been investigated. We have obtained qualitative and quantitative results of the free energy and the

    magnetic susceptibility in graphene nanoribbons. The electronic states in the tight-binding

    approximation were used to calculate the thermal and magnetic properties. In the case of a finite

    magnetic field, the Harper equation was solved for the electronic state for various wavevectors.The

    magnetic field and temperature dependence of the magnetic susceptibility over a wide field and

    temperature range are presented.
