Hown groupsin Figure 4. The reduction of H groups may films withfewer (12 wt )/PVP, since the may be clearly decreased for thinner dielectric be on account of PVA H groups inside BMS-8 supplier shownthinner dielectric films, which led to a lot more productive H elimination through the baking in Figure 4. The reduction of H groups may well be because of fewer H groups withinprocess [26]. dielectric PVA concentration of twelve wt presented quite possibly the most ideal parameters the thinner Thus, the movies, which led to far more productive H elimination via in our examine. the baking approach [26]. So, the PVA concentration of twelve wt presented by far the most suitaFigure 5 examine. ble parameters in ourshows the transfer traits (IDS -VGS ) of the OTFT together with the PVA (twelve wt )/PVP the transfer insulator, single(IDS-Vgate layer, OTFT withPVP gate layer, all of Figure 5 demonstrates bilayer gate qualities PVA GS) of the and single the PVA (12 which have been measured at a single PVA gate layer, and single PVP gate layer, all leakage wt )/PVP bilayer gate insulator, drain voltage (VDS ) of -20 V.
