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.
