Investigation on physical properties of nanosized copper oxide (CuO) doped with cobalt (Co): A material for electronic device application

Abstract

This study has reported about the preparation as well as characterization of Copper oxide (CuO) nanoparticles doped with Cobalt series at low temperature by Sol-gel method. The characterization techniques like x-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, defused reflectance spectroscopy (DRS), and DC measurement has been used to confirm its phase formation i.e. monoclinic, surface porous morphology, the redshift of Raman peaks confirms optical phonon confinement, whereas increasing bandgap signifies the quantum confinement effect. The semiconducting nature of samples has been observed by two probe method. Furthermore, the study has focused in detail on the effect of cobalt doping with varying concentrations by wt % on its structural, morphological, optical, and conductivity features.

Wet-chemical and hydrothermal routes for CuO nanomaterial fabrication are among the most important techniques that are currently under development for critical applications such as in lithium-ion batteries, where wet-chemical methods ensure the fabrication of, for example, electrode materials, [89][90][91] optical materials, 92 photocatalysts, 93 bioactive materials 94 and other functional nanomaterials. 95 Fig.…”

Sol-Gel Fabricated CuO Thin Film: Characterization for Device Application

“…Transition metal oxides (TMOs) have become an essential part of modern technologies that demand both electrical and optical transparency in the visible domain of the electromagnetic spectrum [1]. The thin film based copper oxide (CuO) has been used in many electronic and optoelectronic devices such as thin-film transistors, cross-point memories, gas sensors, and lithium-ion batteries [2] over recent decades. The main advantages of this oxide include low production cost, thermal stability, nontoxicity, and relatively high optical absorption [3].…”
