Transmission and LDOS in case of ZGNR with and without magnetic field

We report and adduced Transmission and LDOS in the presence of magnetic field as well as without magnetic field. We study electronic transport in case of Zigzag structures only. NEGF technique has been used to determined the transport properties and we investigate the effects of magnetic field on the electronic band structure and corresponding conductance as well as LDOS curves. Calculation of the conductance curves of a finite graphene nanoribbon attached to two semi-infinite graphene electrodes in the presence of impurity of the system. Magnetic field is incorporated through Peierls substitution method.
