polymer electrolyte gate dielectric reveals finite windows of high conductivity in organic thin Film transistors at high charge carrier densities
Journal of the American Chemical Society, 2005Co-Authors: Matthew J Panzer, Daniel C FrisbieAbstract: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.

MarkovAbstract:ABSTRACT The possibility was investigated to compress and to split lase r pulses at their nonlinear optical transmission through thin Semiconductor Films. thin Semiconductor Film, biexciton, two-photon absorption, nonlinear transmission, ultrashort laser pulse 1. INTRODUCTION In several recent papers 1-6 , the processes of interaction of resonant laser radiation with excitons and biexcitons in thin Semiconductor Films were studied. A thin Film approximation a llows one to reduce the set of nonlinear partial differential equations for the field and medium to a relatively simple set of ordinary differential equations, which in some cases can be solved analytically. The recent considerable advances in the creation of dimensionally confined Semiconductor structures stimulate the research of nonlinear optical properties of thin Semiconductor Films. This research is also of practical interest owing to a wide spectrum of possibilities while using thin Films for the development of systems for ultrafast optical processing of information. In the present paper the results are described of a theoretical investigation of the effects of nonstationary nonlinear transmission of short pulses of resonant laser radiation through a thin Semiconductor Film in the conditions of two-photon generation of biexcitons from the crystal ground state.
