title: Polymer electrolyte gate dielectric reveals finite windows of high conductivity in organic thin film transistors at high charge carrier densities.
abstract: Finite regions of high conductivity were observed in both n- and p-channel organic thin film transistors based on polycrystalline organic semiconductor films and a solution-processed, solid polymer electrolyte gate dielectric. The transition from a highly conductive state to a more insulating state with increasing gate bias may be attributed to the realization of carrier densities greater than 1014 charges/cm2 in the semiconductor film.
