Steady State Formalism for Electron Transfer through DNA System: Ladder Model

S. A. Al-Seadi | J. M. Al-Mukh | S. I. Easa

Abstract: General steady state formalism for the transmission probability for electron transfer through DNA system is derived, by assuming DNA system chain as one scattering region bounded by two strands. The ladder model is considered to calculate the energy spectrum of the DNA system. The transmission probability calculations are employed to calculate I-V characteristics and the temperature-conductance dependence which are found to be comparable in behavior with other findings.

Keywords: Nano science, DNA, ladder model, I-V characteristics, transmission probability
