Magnetoconductivity of two-dimensional Dirac cones and gapped nodal-rings under impurity-potentials in the ultraquantum limit
The study investigates how disorder affects electricity in 2D Dirac cones and gapped nodal rings under strong magnetic fields. It found that GNRs show oscillatory conductivity and a sawtooth Hall effect due to their unique energy spectrum, unlike simple Dirac cones where transport is smoother. Disorder type dictates the shape of these effects.
