摘要：
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).
