It demonstrates the negative correlation concerning film thickness and capacitance. of 500 500 nm. It demonstrates the adverse correlation amongst film thickness and capacitance. The frequency of capacitance measurement The dielectric frequent of your high-K The frequency of capacitance measurement was 1 kHz. was one kHz. The dielectric frequent from the high-K PVP bilayer with the PVAwith the PVA concentration at twelve wt using and (two) PVA/low-K PVA/low-K PVP bilayer concentration at twelve wt using Equations (1) Equations calculated to become calculated to be 5.6. The calculated dielectric continual with the high-K was (1) and (two) was 5.six. The calculated dielectric continuous of your high-K PVA/low-K PVP PVA/low-K PVP bilayer construction was Bafilomycin C1 Description smaller than PVA from the which was reported to become bilayer structure was smaller sized than that of your single that layer, single PVA layer, which was [24] and wasbe 9.2 [24] and wasthe single PVP layer, which was reported whichabout 9.2 reported to bigger than that of greater than that of your single PVP layer, to get was reported to become aboutproposed high-K PVA/low-K PVP PVA/low-K PVP bilayer certainly 3.5 [25]. As a result, the three.five [25]. Thus, the proposed high-K bilayer structure could structure could obviously increase the helpful capacitance in comparisonwith the single PVP layer, boost the effective capacitance in comparison to that attained to that attained using the single PVP layer, leading to ancurrent [11,12]. latest [11,12]. resulting in an increased drain increased drainPolymers 2021, 13, x FOR PEER REVIEWPolymers 2021, 13,five of5 of8.0 7.five seven.0 six.5 six.0 5.5 five.0 4.5 4.0 3.five three.0 2.five two.0 1.five 1.0 0.five 0.0 -Capacitance (10-9F/cm2)PVA@25Wt / PVP PVA@16Wt / PVP PVA@12Wt / PVP—-1 0 1 Voltage (V)Figure 3.

For that reason, the cross-linking PMF as a result of thecan be evaluated by Fouriera cross-linking process. Hence, the crossefficiency curing stage, that is referred to as transform infrared (FTIR) to measure the quantity linking efficiency could be evaluated by the FTIRtransform infrared (FTIR) to gate dielectric with of H groups.
