Hown groupsin Figure four. The reduction of H groups may well films withfewer (twelve wt )/PVP, because the may be obviously decreased for thinner dielectric be because of PVA H groups within shownthinner dielectric films, which led to a lot more efficient H elimination through the baking in Figure four. The reduction of H groups could possibly be as a result of fewer H groups withinprocess [26]. dielectric PVA concentration of twelve wt presented essentially the most ideal parameters the thinner Hence, the movies, which led to much more effective H elimination via in our study. the baking process [26]. Hence, the PVA concentration of 12 wt offered essentially the most suitaFigure five review. ble parameters in ourshows the transfer qualities (IDS -VGS ) of your OTFT with the PVA (12 wt )/PVP the transfer insulator, single(IDS-Vgate layer, OTFT withPVP gate layer, all of Figure five displays bilayer gate qualities PVA GS) from the and single the PVA (twelve which had been measured at just one PVA gate layer, and single PVP gate layer, all leakage wt )/PVP bilayer gate insulator, drain voltage (VDS ) of -20 V.
