title: Organic thin film transistor with poly(4-vinylbiphenyl) blended 6,13-bis(triisopropylsilylethynyl)pentacene on propyleneglycolmonomethyletheracetate dielectric surface.
abstract: This paper presents the latest results in the use of soluble materials, such as organic semiconductors (OSCs) and gate-dielectrics, for simplified processing of organic thin film transistors (OTFTs). In this work, the fabrication of a solution-processed OTFT, with 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) and TIPS-pentacene mixed with poly(4-vinylbiphenyl) (PVBP) as the OSC, and propyleneglycolmonomethyletheracetate (PGMEA) as the gate-dielectric, is described. From electrical measurements, we observed exemplary I-V characteristics for these TFTs. Device performance characteristics have been obtained, including the charge carrier mobility (micro) of 1.47 x 10(-2) cm2Ns, threshold voltage (V(T)) of -11.36 V, current on/off ratio (I(ON/OFF)) of 1.08 x 10(4), sub-threshold swing (SS) of 2.13 V/decade for an OTFT with PVBP blended TIPS-pentacene and micro of 1.39 x 10(-4) cm2/Vs, V(T) of 0.7 V, I(ON/OFF) of 1.64 x 10(3), SS of 4.21 V/decade for an OTFT without polymer binder, individually.
