Summary: | <p>Abstract</p> <p>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 <it>G</it> <sub> <it>0</it> </sub>, <it>i</it> <sub> <it>0</it> </sub>, and <it>T</it> <sub> <it>1d</it> </sub> are determined empirically, and the conductivity is estimated for samples of poly(dA)–poly(dT).</p> |
