Polaron Hopping in Nano-scale Poly(dA)–Poly(dT) DNA

Polaron Hopping in Nano-scale Poly(dA)–Poly(dT) DNA

<p>Abstract</p> <p>We investigate the current&#8211;voltage relationship and the temperature-dependent conductance of nano-scale samples of poly(dA)&#8211;poly(dT) DNA molecules. A polaron hopping model has been used to calculate the I&#8211;V characteristic of nano-sca...
