Abstract—A theoretical model of electron tunneling current
in a p-n junction made from strained armchair
graphenenanoribbon (AGNR) was developed. The effect of
strain to the energy dispersion relation of AGNR was
formulated under the tight binding method. The energy
bandgap of AGNR was then analytically determined.
Furthermore, the electron transmittance was calculated by
utilizing the Airy wavefunction-approach. Finally, the
calculated transmittance was used to obtain the tunneling
current by employing the Landauer formula. The effects of
strain to the energy band gap, AGNR width, and tunneling
current were studied thoroughly.
Index Terms—Graphene, AGNR, tight binding, strain, band gap, p-n junction, Airy wave function, tunneling current.
