Polaron Hopping in Nano-scale Poly(dA)-Poly(dT) DNA.
We investigate the current-voltage relationship and the temperature-dependent conductance of nano-scale samples of poly(dA)-poly(dT) DNA molecules. A polaron hopping model has been used to calculate the I-V characteristic of nano-scale samples of DNA. This model agrees with the data for current versus voltage at temperatures greater than 100 K. The quantities G(0), i(0), and T(1d) are determined empirically, and the conductivity is estimated for samples of poly(dA)-poly(dT).
