Description
A tight-binding model of carbon superlattice structures with randomly distributed hopping parameters is developed to interpret the effective nitrogen doping effect on large transmission coefficients of electrons. The calculated current density explains successfully the device characteristics of multilayered carbon including layered graphene structures at low temperatures and high magnetic fields.
