MAGNETIC FIELD-DEPENDENT ELECTRIC CURRENT ON A PERIODIC POLY(DA)-POLY(DT) DNA MOLECULE STRUCTURE

An electric current flowing on the Poly(dA)-poly(dT) DNA molecule structure has been calculated. The was calculated from transmission probabilities by employing Landauer-Buttiker formalism. Green’s function technique used for obtaining probabilities. modeled within tight-binding Hamiltonian model approach. takes into account electron hopping parameters which are dependent magnetic field as well field. presence of a causes Peierls phase factor parameters. calculation results at low voltages show that after decreasing, oscillates with However, higher voltages, is increasing and
