One step hydrothermal synthesis of SnO 2 -RGO nanocomposite and its field emission studies

Uncovering the origin of enhanced field emission properties of rGO–MnO2heterostructures: a synergistic experimental and computational investigation

“…A comparison between the turn-on eld values obtained in the present study and previously reported MnO 2 nanostructures and the MnO 2 /rGO nanoheterostructures is provided in Table 1. 21,22,[61][62][63][64][65][66] The Fowler-Nordheim (F-N) plot for MnO 2 nanorods and rGO/MnO 2 nano-heterostructure obtained from ln(J/E 2 ) verses (1/E) is shown in Fig. 3(c and d).…”

Carbon Nanotube-Based 2-Dimensional and 3-Dimensional Field Emitter Structures

“…The instantaneous difference in the local electric field is due to continuous ion bombardment by released electrons from ionized residual gas molecules, which may lead to variation in geometrical factors via a change in curvature radius at the site of emission, thus changing the strength of the 'local' electric field. 26,27 Table I represents a comparison of field emission features of this research with the CNTs on foil-and foam-based emitters reported in the literature. This list illustrates that both turn-on field and field enhancement factor are better than several other literature reports on CNT-based cathode emitters prepared on foils and foams.…”

Facile Fabrication of Au Nanoparticles/Tin Oxide/Reduced Graphene Oxide Ternary Nanocomposite and Its High-Performance SF6 Decomposition Components Sensing

“…When the sensor was in contact with the incoming gas, the change in resistance throughout the process was recorded by the electrochemical workstation. Due to the corrosive nature of the SF 6 decomposition components, there may be some changes in sensor parameters after prolonged exposure to these gases (Petrila et al, 2016; Bansode et al, 2017; Manikandan et al, 2018); however, the effects of such variations will not be discussed in this study. The gas flow rate was controlled to 500 ml/min.…”
