Abstract :
In this paper, we report the first results on DNA based thin film field effect transistors (TFFET). The DNA molecules are extracted from Salmon´s milt and roe sacs and purified to 96%. DNA based thin films are obtained using different techniques including spin coating, molecular beam deposition (MBD), pulse laser deposition (PLD)...etc. An increase in the overall charge carrier mobility was achieved by blending the DNA molecules with conductive polymers such as PEDOT:PSS as well as conductive nanoparticles such as single wall carbon nanotubes. MOSFETs with bottom gate, bottom contact structures using DNA based thin films as the semi-conductive layer have been developed.
