Fabrication and Characterization of Copper Oxide Nanoparticles/PSi Heterodiode

Abstract

Copper oxides are one of the metal oxides , that has been studied for several reasons such as the nature and their reasonably good electrical and optical properties by Cu2O Copper formed two known oxides : cupric (CuO) and curprous (Cu2O) were p-type with a band gap energy 1.21 to 1.51 eV and 2.1 to 2.6 eV respectively [1-3]. On the other hand CuO with different nanoshape has been synthesized by different methods in many research papers [4-10]

Study the optical and Antibacterial properties of the Ag Nano-Particles by Exploding of Wire technique

“…Figure ( 4) illustrates the reflectance spectrum and refractive index as a function of wavelength in the range of 250-800 nm for Ag NPs. The reflectance (R) and refractive index were calculated for the samples using equation(1) [10], [11]. R+T+A=1 ………………………..1 Where T: Transmittance A: Absorbance R: Reflectance…”

Synthesis and characterization of thin films of P3HT − G/MoS2 nanocomposites in photodetectors applications

“…[1][2][3][4][5][6] Photovoltaic devices can almost be categorized as large-scale broadband or selective selectors, such as Si and InGaAs, which respond to energy powered photons higher than their difference gaps. 7,8 Selective photodetectors, also known as narrowband photodetectors, are designed to detect light at a specific wavelength and generally are applied for biomedical imaging and safety surveillance. 9 Both broadband and selective properties are required to build optical detectors, which show a good optical response to a broad spectrum and are still spectrally distinctive.…”
