“…Besides the extensive use of already mentioned CH 3 CN and various alkylamines, arylalkylamines, and arylamines as NCNTs precursors, NCNTs were successfully prepared by pyrolysis of functional amines, e.g., monoethanolamine [164][165][166], and amides, e.g., carbamide (urea) [167], N,N-dimethylformamide [49,50,105,168,169], and dicyandiamide [170], or mixtures containing amides, e.g., N,N-dimethylformamide/camphor [168], N,Ndimethylformamide/cyclodextrin [169], and (N-phenylcarbamoyl)ferrocene/toluene [171].…”

The performance and characteristics of a hybrid heterojunction single-walled carbon nanotube and GaAs solar cell are modelled and numerically simulated using AMPS-1D device simulation tool. The device physics and performance with different junction parameters are analysed. The results suggest that the open-circuit voltage changes very slightly by changing the electron affinity, acceptor and donor density while the other electrical parameters reach an optimum value. Increasing the concentration of a discrete defect density in the absorber layer decreases the electrical parameters. The current-voltage characteristics, quantum efficiency, band gap, and thickness variation of the photovoltaic response will be quantitatively considered.

“…There is no agreement on the value of current density to be specified and the definition of turn-on and threshold field, it is determined by the group research themselves. For example, Ghosh et al [4,5] and Srivastava et al [6] defined turn-on and threshold field to be the field required by the film to produce current density of 10 µAcm -2 and 1 mAcm -2 respectively. While Bonard and co-worker [90] specified the current density of 10 µAcm -2 and 10 mAcm -2 respectively.…”

Zinc oxide (ZnO)/carbon spheres (CS) nanocomposites were successfully synthesised using waste engine oil as precursor for the CS production. ZnO nanorods were grown using sol-gel immersion method with MgZnO as the seeded catalyst and thermal chemical vapour deposition was used to synthesise CS. Different configurations of ZnO/CS structures were prepared i.e. CScoated ZnO and ZnO-coated CS. The structures of composite samples were analysed using field emission scanning electron microscopy (FESEM), Energy-Dispersive X-ray (EDX), micro-Raman and X-ray Diffraction Spectroscopy (XRD). FESEM observations revealed the structural changes of pristine ZnO and CS in composite structures. The as-present of ZnO or CS was believed to affect the subsequent growth of another structure. Field electron emission (FEE) properties of both nanocomposites were also investigated. It was found that ZnO-coated CS sample has better FEE properties with lower turn-on (3.48 Vµm-1) and threshold field (6.35 Vµm-1) obtained at current density of 0.1 and 1 µAcm-2 , respectively. This study highlighted that nanocomposites of ZnO and CS have successfully enhanced the field emission performances of materials compared with pristine ZnO or CS due to the structural changes of material emitter.
