N2 - The diagonal hopping dependent I-V characteristic of a periodic DNA molecule has been studied. Exponentially twisting angle dependent hopping constant is used in the calculation. The diagonal hopping constant is modeled using semi-empirical Slater-Koster theory. A 32 base pairs doubled-stranded Poly(dG)-poly(dC) DNA molecule model sandwiched in between two metallic electrodes is used in the calculation of I-V characteristic using Landauer-Buttiker formalism by assuming symmetric voltage drop at the contacts. The I-V characteristics is calculated from the transmission probability of charge on the molecule calculated using transfer and scattering matrix methods, simultaneously. The results show that generally, as the vibration and diagonal hopping coupling constant increases, the current magnitude increases. However, at low voltage the increment of current is minute. These trends are observed in the I-V characteristic of DNA molecule for all frequencies and temperatures used.
