Abstract

PLAZAS, C. A.; FONSECA-ROMERO, K. M.  and  REY-GONZALEZ, R. R.. Probabilidad de transmisión en cadenas desordenadas de ADN. Rev. mex. fis. [online]. 2014, vol.60, n.5, pp.376-383. ISSN 0035-001X.

In the last years have grown the interest to use nucleic acids and proteins in nanodevices. However, some their electronic properties remain unclear and there is still much more to be done. We address the problem of charge transport across a finite segment of DNA, using a linear chain model into tight binding framework with nearest neighbors interaction and one orbital per site to represent the DNA. Hydrations effects are taken into account as random variations of the self-energy. Transmission probability is calculated from transfer matrix concept.

Keywords : DNA; transmission probability; disorder.
