Abstract
The electrical transport properties of DNA films in field‐effect transistor structure are analyzed. As‐depositedfilms did not show electrical conductivity; no DNA network wasobserved between the DNA moleculesbridging the electrodes. When the DNA molecules were stretchedinto a thin film an interpenetratingnetwork formed, and the devicesshowed pronounced field‐effects withambipolar behavior. Devices producedby electrostatic trapping of DNA molecules exhibited large bulk parallelcurrents and relatively small field effects.
