  6. 15. Strain-induced nonlinear Hall effect in graphene systems

    University essay from Stockholms universitet/Fysikum

    Author : Pedram Pakmehr; [2022]
    Keywords : ;

    Abstract : This thesis aims to study the nonlinear electrical transport response of monolayer and bilayer graphene systems under the influence of different lattice deformations (strain). Broken inversion and rotation symmetries can generate a second-order transverse current response called the nonlinear Hall effect in the presence of time-reversal symmetry. READ MORE
