Abstract

We investigated DC and RF transport characteristics of lambda DNA molecules. Our DNA film device with a coplanar waveguide structure exhibited reliable high-frequency characteristics and sufficiently small leakage currents. The DC gate response of the DNA transistor showed nonlinear transport properties and resistance decreased as V_G became increasingly negative. It suggests that lambda DNA behaves as a p-type semiconductor. The RF pulse response of the lambda DNA transistor showed an increase in average current with increase in the frequency. The observed frequency characteristics can be explained by AC heating, and our observation suggests that the conductivity of DNA molecules increases with temperature.
