Abstract

The temperature dependence of I-V curves for poly(dA)-poly(dT) and poly(dG)-poly(dC) DNA molecules trapped between two metal electrodes was studied. For both samples, most experimental results except the temperature dependence of the hopping distance for poly(dA)-poly(dT) are interpreted within the polaron hopping model. The gate-voltage effect on the I-V curve was also measured. It was found that poly(dA)-poly(dT) exhibits n-type semiconducting behaviors, while poly(dG)-poly(dC) does p-type ones.
