Development of hierarchical copper sulfide–carbon nanotube (CuS–CNT) composites and utilization of their superior carrier mobility in efficient charge transport towards photodegradation of Rhodamine B under visible light

Abstract

In this work, the synthesis of visible light sensitive copper sulfide (CuS) nanoparticles and their composites with carbon nanotubes (T-CuS) via a solvothermal technique has been reported. The synthesized nanoparticles...

Fabrication and Characterization of Metal/Semiconductor Junction Devices Using Four Benzaldehyde Derivatives

“…The device performance depends on the transit time and the mobility of the carriers. Mobility of the charge carrier means that the drift velocity of the charge carrier per unit applied electric field.so, it defines how fast the charge carrier can swift from one place to the other place.The mobility is calculated from the I versus V 2 plot (Figure 2) by using the Mott‐Gurney equation: [25,26] $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr I={{9{\mu }_{eff}{\varepsilon{} }_{0}{\varepsilon{} }_{r}A}\over{8}}\left({{{V}^{2}}\over{{d}^{3}}}\right)\hfill\cr}}$$$ …”

Orange peel biochar/clay/titania composites: low cost, high performance, and easy-to-reuse photocatalysts for the degradation of tetracycline in water

“…Generally, a low emission intensity indicates a decreased recombination rate of the photogenerated electron/hole pairs and thus a higher photocatalytic activity. 15,65,66…”

Development of a novel Cd(ii) metal complex for solvent-sensitive detection of Zn(ii) and Mg(ii) with the formation of Cd(ii)–Zn(ii)/Cd(ii)–Mg(ii) complexes and their application in effective Schottky devices

“…A longer transit time indicates a higher trapping probability. 54 The above discussion strongly established that Device-1 will be an effective Schottky device. The low band gap value for complex 2 is crucial for it to exhibit more optimal electrical properties.…”
