dc.description.abstract | We investigate the charge transport in synthetic DNA polymers built up
from single types of base pairs. In the context of a polaron-like model,
for which an electronic tight-binding system and bond vibrations of the
double helix are coupled, we present estimates for the electron-vibration
coupling strengths utilizing a quantum-chemical procedure. Subsequent
studies concerning the mobility of polaron solutions, representing the state
of a localized charge in unison with its associated helix deformation, show
that the system for poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers,
respectively possess quantitatively distinct transport properties.
While the former supports unidirectionally moving electron breathers attributed
to highly efficient long-range conductivity the breather mobility
in the latter case is comparatively restrained inhibiting charge transport.
Our results are in agreement with recent experimental results demonstrating
that poly(dG)-poly(dC) DNA molecules acts as a semiconducting
nanowire and exhibits better conductance than poly(dA)-poly(dT) ones. | es |
