Numerical simulation of field emission efficiency of anodic aluminum oxide carbon nanotube field emitter in the triode structure

A method for the extraction of the voltage-dependent quantum capacitance of carbon nanotubes usingab initiosimulations

“…In addition to the quantum capacitance calculation, Fermi velocities of electrons in the CNTs are also calculated using the quantum capacitance values obtained from equation (5). The variation of average Fermi velocity with applied bias voltage is plotted in figure 5.…”

“…CNTs are rolled-up sheets of two-dimensional (2D) graphene crystals, which are metallic or semiconducting depending on their chirality. Semiconducting CNTs are generally used for implementation of nanoscale FETs [5], while metallic CNTs are suitable for interconnect realization for very large-scale integrated circuit (VLSI) technology because of advantages such as ballistic electron transport [6]. Metallic CNTs are viewed as good candidates for interconnects in VLSI circuits because they allow current densities up to 10 9 A cm −2 as a result of ballistic electron transport [7][8][9].…”

Local field enhancement dependence on nanoparticle's geometry in Au/TiO<inf>2</inf>/Ti/Si SERS-active substrate for biochemical sensors

“…Then, we base on Yee's mesh and the electric and magnetic field components at points on a grid with grid points to solve these equations. The Maxwell's equations are iteratively solved in a leapfrog manner, alternating between computing the E and H fields at subsequent Δt / 2 intervals [4,5].…”

Optimized Distribution and Morphology of Carbon Nanofibers for a Field Emitter Grown by Nickel and Chromium Cosputtering

“…When the distance between adjacent patterns of synthesizing CNFs is at least twice the CNF length, they found that the field strength focused on those CNFs was almost the same as a CNF standing alone. There are many reports on the optimization of FE properties with CNF array patterning that followed the reports of Nilsson et al [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In some these reports, the patterning of CNFs by lithography, which commonly uses semiconductor process technology, was explained.…”
