Simulation of Process Parameters for the Growth of Ba-Doped ZnO Nano-Rods Using Fuzzy Analysis

Abstract

Advancement in technology and industrialization has made nano-technology a significant research area. Among the wider field of nano-technology, nano-materials are considered as the future of research and applications. Due to their unique properties, nano-materials are gaining enormous attention in the field of energy, medical, electronics and chemistry. These materials exhibits advanced properties and provide large surface area to volume ratio due to decrease in their rod dimeter. Between other nano-materials, ZnO (Zinc Oxide) nano-structures are extensively known due to their excellent piezo and pyro electric properties. Various materials are doped with ZnO to decrease its rod diameter for advanced application. In this work, we have fabricated, simulated and studied Barium doped ZnO nano-rods and their effect on the rod diameter using fuzzy analysis. The result depicts that the rod diameter decrease with increase in barium doping and process temperature for the growth of ZnO nano-rods. The simulated results are compared with the fabricated results and the calculated results, with less than 1% error in the value. The fabricated Ba (Barium)-doped ZnOnano-rods are highly symmetric and show hexagonal geometry. The size of the nano-rods is also similar to the Mamdani model simulated results. Ba-doped ZnO nano-rods are thus suitable for nano-scale applications including energy harvesting and bio-medical applications.
