Voltage-current Characteristics of Multi-dimensional Semiconductor Devices*

|The steady state drift-diiusion model for the ow of electrons and holes in semiconductors is sim-pliied by perturbation techniques. The simpliications amount to assuming zero space charge and low injection. The limiting problems are solved and explicit formulas for the voltage-current characteristics of bipolar devices can be obtained. As examples, the pn-diode, the bipolar transistor and the ...

S-shaped current-voltage characteristics of organic solar devices

Measuring the current-voltage characteristic of organic bulk heterojunction solar devices sometimes reveals an S-shaped deformation. We qualitatively produce this behavior by a numerical device simulation assuming a reduced surface recombination. Furthermore we show how to experimentally create these double diodes by applying an oxygen plasma etch on the indium-tin-oxide anode. Restricted charg...

Understanding anomalous current-voltage characteristics in microchannel-nanochannel interconnect devices.

The integration of a microchannel with a nanochannel is known to exhibit anomalous nonlinear current-voltage characteristics. In this paper, we perform detailed numerical simulations considering a 2-D nonlinear ion transport model, to capture and explain the underlying physics behind the limiting resistance and the overlimiting current regions, observed predominantly in a highly ion-selective n...

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...
