Abstract

Sensitivity of Nanostructured Mn-Doped Cobalt Oxide Films for Gas Sensor Application

Highlights

Among the different transition metal oxides (TMO), Co3O4 is an imperative p-type semiconductor [1, 2]
A few procedures have been utilized to enhance the conduct of metal oxides by methods for presenting different dopants [18], shaping nanocomposites with p-n intersection [19], and by tuning the morphology [7], have focused on the electrical and surface properties of nanoparticles to accomplish enhanced reactant, electro-optical, attractive, substance, and physical properties [20]
Note that the effect doping concentrations increasing up to 3% did not change the phase of cobalt oxide, and these were the most important conditions of doping, as well as through the alteration in intensity of scattering for the peaks produced

Summary

Introduction

Among the different transition metal oxides (TMO), Co3O4 is an imperative p-type semiconductor (coordinate energy bandgap at 1.48 and 2.19 eV) [1, 2]. Metal oxide nanostructures play an essential role in numerous locales of science, physical science, ecological science, and material science [8,9,10] These TMO, while falling in the nano estimated administration, are relied upon to have significantly witnessed an increasing interest in the fields; for example, information stockpiling, spintronics biomedicine, and http://www.nanobe.org broadcast communications [11,12,13,14]. A few procedures have been utilized to enhance the conduct of metal oxides by methods for presenting different dopants [18], shaping nanocomposites with p-n intersection [19], and by tuning the morphology [7], have focused on the electrical and surface properties of nanoparticles to accomplish enhanced reactant, electro-optical, attractive, substance, and physical properties [20]. This work aims to consider the effect of deformation on the sensitivity of the deposited films for NO2 gas
