Current-Voltage Characteristics of Multiple Bare Tethers as Electron Collector

Current { Voltage Characteristics of Two { Dimensional VortexGlass

We have performed Monte Carlo simulations to determine current{voltage characteristics of two vortex glass models in two dimensions. Our results connrm earlier studies which concluded that there is a zero temperature transition. Additionally we nd that, as the temperature approaches zero, the linear resistance vanishes exponentially, and the current scale, J nl , where non-linearities appear in...

Nonlinear current-voltage characteristics of nanochannels.

Like ion channels, nanochannels are known to exhibit curious non-Ohmic current-voltage (I-V) characteristics with an approximate piece-wise constant differential resistance. Using a nanoslot model and a nonequilibrium ion transport theory, we attribute the nonlinear resistance to overlapping double layers inside and an extended polarized layer of space charge outside the nanochannel. The overli...

Apparent secondary-electron emission coefficient and the voltage-current characteristics of argon glow discharges.

The accuracy of secondary-electron emission coefficients, that are used as input data of discharge models, seriously influences the calculated discharge characteristics. As it is very difficult to consider all possible electron emission processes of a cold cathode separately, in most of the recent models an apparent secondary coefficient gamma is applied, which is often assumed to be constant, ...

Understanding Langmuir probe current-voltage characteristics

I give several simple examples of model Langmuir probe current-voltage I-V characteristics that help students learn how to interpret real I-V characteristics obtained in a plasma. Students can also create their own Langmuir probe I-V characteristics using a program with the plasma density, plasma potential, electron temperature, ion temperature, and probe area as input parameters. Some examples...
