Abstract :
Thin films of zinc oxide nanoparticles (ZnO NPs) for bistable device was prepared by electrostatic spray deposition technique based on an indium-tin oxide/ZnO NPs/aluminum (ITO/ZnO NPs /Al) structure. The characterizations of ZnO NPs films were performed using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM). The influence of the deposition time on properties of films was also investigated. Moreover, the effect of deposition time on the bistable properties can be performed by current-voltage (I-V) measurements. The conduction mechanism of the bistable device was analyzed by theoretical model.
