Abstract
Fuzzy logic has been considered as a viable method for every field of study because of its large number of applications and advantages. In nano-materials, structural knowledge of material and parametric estimation can be studied using fuzzy logic. The main objective of this work is to perform fuzzy logic analyis for parametric estimation of Zinc oxide (ZnO) nano-rods based structures. The zinc oxide nano-rods when prepared with doped metal that results in change in properties of Zinc oxide nano-rods. These properties include structural, optical, mechanical and electrical properties of ZnO nano-rods. The enhancement in properties make the doped ZnO based material suitable for energy harvesting, bio-medical, energy and electronics application. Literature depicts the effect of 2nd group elements on ZnO nano-particles which directly shows the effect of change of parameters due to change in doping concentration. In this work, the analysis of effect on bandgap and rod diameter due to change in doping concentration and synthesis time is performed on ZnO nano-rods with doping 2nd group elements. The authors concluded that the synthesis time increase the rod diameter which directly decreases the bandgap. However, the doping concentration of 2nd group elements results in increase in band gap and decrease in rod diameter. However this effect is negligible for Mg and Be due to there small atomic size. The comparison between fuzzy logic simulation and mamdani model were also analysed which shows an error of less than 1% between the value. The 2nd group doped ZnO nano-rods can be used for various application due to adjustable band-gap and rod diameter with change in doping concentration.
