摘要：
The effect of pulse amplitude on the switching properties of cesium nitrate: poly (vinyl alcohol) composite film at room temperature has been studied. The switching response of the composite film was studied using the bipolar square pulses. The switching current transients were analyzed using finite grain model (FGM) and infinite grain media (IGM). The Matlab programming based upon the assumptions of FGM and IGM theories is used to fit the experimental data with the theoretical. The microscopic parameters such as effective dimensionality, switching time, nucleation rate, and domain wall velocity have been estimated. The polarization current and domain wall velocity exhibited exponential dependence on the pulse amplitude.
