Visible Ranges Photo Detector Fabricated Based on Nano Copper Oxide Deposited by Reactive Pulsed Laser Deposition

Abstract

This manuscript presents the reactive pulsed laser deposition method was used to prepare and deposit the high-quality copper oxide (Cu2O) Nanofilms using high purity copper metal, Oxygen, and heating at 300 C, at different laser energies rated (800 mj, 1000 mj, and 1200 mj) respectively. The presented results show high ranges of transparent values with the increasing laser energies from 66%-90%. As the laser energies increased the optical energy band gap value was increased from 2.32eV – 2.47eV. Further, the AFM, XRD, I-V, and spectral response tasted and investigated the surface topography, homogeneity, roughness’s, structural and optoelectronic properties for the deposited Cu2O nanofilms, respectively.
