Abstract

The synthesis of carbon nitride supported lead oxide nanoparticles (CNLO) has been reported by the pyrolysis of urea under ambient pressure and high-temperature conditions in the presence of lead nitrate. The X-ray diffraction analysis confirmed the formation of α-PbO, and the microscopic image showed highly dispersed oxide nanoparticles on the carbon nitride matrix. The optical property exhibited the characteristics vibrational bands that indicate the presence of the graphitic form of carbon nitride structure in the synthesized material. The electrical property of the device made with CNLO, as active material, showed the bipolar resistive switching effect with moderately high ON to OFF ratio, where the transport property of the device was justified by the Poole-Frenkel emission and ohmic conduction mechanism for the low and high conductance states, respectively. The device showed a sustained amount of endurance and retention property with a comparable ON-OFF ratio. The aptitude of processing, storing and recovering of binary information using CNLO based device, with the size of 8-bit, was also demonstrated in this study.
