Hybrid composited material like polymer-ceramic will improve the reliability factor of the device. Yet, the motivation still goes on to produce high performance device. In this study, the impedance analysis on bilayer films lead titanate and poly(vinyledenefluoride-trifluoroethylene) yield to the semicircle cole-cole plot with added slanted spike results. This presents the double layer capacitance...
Development of innovative device design was fully utilized to fabricate hybrid composited PVDF-TrFE/PbTiO3 that having bilayered films capacitors. Step by step of layer deposition trough spin coating method had performed an optimal thickness of ∼ 319 nm PbTiO3 first layer and ∼470 nm polymer second layer. It was found that averagely 55.6 nm multigrain size of PbTiO3 performed high densification films...
The thin films of lead titanate (PbTiO3) have been prepared on ITO coated glass substrate by means of storage element for DC power application. The solution was prepared by modified sol-gel process that involved sonication process to ensure the uniform nanoparticulates formation before ageing stage take parts. In the need to compensate the lead loss, extra 10mol% of Pb content was added to the solution...
This paper reports on the effects of annealing process on the dielectric properties of lead titanate (PbTiO3) thin films. The thin films have been deposited on silicon substrates using sol-gel spin coating method. The dielectric properties and resistivity of the thin films annealed at different annealing temperatures and times were then investigated using HIOKI 3532-50 LCR meter and four point probe...
Lead Titanate (PbTiO3) thin films derived from metal alkoxide precursor solution through sol-gel method were deposited onto silicon substrates by dip coating. These films were deposited at different immersing times. The withdrawal speed on the other hand was fixed at 7 mm/s. The dielectric properties of these thin films were investigated as a function of frequency. The IV characteristics and micro-structural...
