A donor cell approximation of the charge flow equation is developed, which includes a method of transferring charge from the contacting electrodes. Because a surface charge distribution has no thickness, its incorporation into a normal electrostatics routine is difficult. The method we adopt applies ...
ed current flow?]]>We consider the behaviour of the solutions of Langmuir''s equation in the phase-plane and in particular we discuss the nature of the singular points and the directions of the asymptotes. It is shown that the isoclines of the equation are a family of conies passing ...
where e is the electron charge, n+ is the density of positive ions, Δφ is the voltage drop in charge region, ρ is density and U∞ is flow speed. It is suggested that equation (1) leads to a value of close to unity for appreciable flow control. Therefore using this equation, and...
the main TENG. Consequently, charges would transfer from the main TENG to the charge storage capacitorCSto reach an equilibrium state. In the following contact process, the charges would flow back to the main TENG and generate power. The charge densityσM0andVEcan be described by equation (1...
We find that photogenerated electrons are transferred to the catalytic surface quasi-ballistically through inter-facet hot electron transfer on a subpicosecond timescale, whereas photogenerated holes are transferred to a spatially separated surface and stabilized through selective trapping on a microsecond ...
As the magnetic field is expected to decrease rapidly as a function of time, it is interesting to understand what effect a strong magnetic field may have on the produced particles and observables like elliptic flow. While only the order of magnitude of the initial field is known, signatures ...
In practice, a small emittance of the center slice may be sufficient to fulfill the emittance criterion of eqn [64] –if this slice has at the same time a high peak current and a small energy spread. It is important to note that the projected emittance measured at the gun exit or after...
In this way, Janus AC-FFET proposed herein greatly facilitates simultaneous active pumping and mixing of stratified analyte streams with a simple device geometry. (F) A sketch of the 2D computation domain used in current numerical simulation. Therefore, we coin the term “Janus AC flow-field-...
e.g. 1/20C or less. To eliminate the overpotential due to the small current, often the average value of the discharge and charge curve is used.Fig. 2shows the measurement of the open circuit voltage after 30min rest time in discharging and charging direction. To our knowledge there is no...
