Electronic transport properties of pristine, homogenously and heterogeneously boron-nitrogen doped saw-tooth penta-graphene nanoribbon (SPGNR) with carbon nanotube electrodes have been studied using Extended Huckel Theory in combination with the non-equilibrium Green’s function formalism. CNT electrodes produce a remarkable increase in current at higher bias voltages in pristine SPGNR. The current intensity is maximum at higher bias voltages, while the nitrogen-doped model shows current from the onset of the bias voltage. However, there are also considerable differences in the I-V curves associated with the pristine model and other models doped homogenously as well as heterogeneously with boron and nitrogen. The doped models also exhibit a small negative differential resistance effect, with much prominence in the nitrogen-doped model. In summary, our findings show clearly that doping can effectively modulate the electronic and the transport properties of penta-graphene nanoribbons that have not been studied and reported thus far.
