The model takes into account the one-dimensional character of the system and the presence of disorder in the DNA double helix. Percolation-theoretical considerations lead to analytical expressions for the high temperature multiphonon-assisted small polaron hopping conductivity, the hopping distance and their temperature dependence. The experimental data for lambda phage DNA (λ&lt;em&gt;-&lt;/em&gt;DNA) and poly(dA)–poly(dT) DNA follow nicely the theoretically predicted behaviour (EQUATION). Moreover, our model leads to realistic values of the maximum hopping distances, supporting the idea of multiphonon-assisted hopping of small polarons between next nearest neighbours of the DNA molecular 'wire'. The low temperature case is also investigated.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 25</style></notes></record></records></xml>
