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 (μ) of 1.47 × 10 -2 cm 2/Vs, threshold voltage (V T) of -11.36 V, current on/off ratio (I ON/OFF) of 1.08 × 10 4, sub-threshold swing (SS) of 2.13 V/decade for an OTFT with PVBP blended TIPS-pentacene and μ of 1.39 × 10 -4 cm 2/Vs, V T of 0.7 V, I ON/OFF of 1.64 × 10 3, SS of 4.21 V/decade for an OTFT without polymer binder, individually.
