A compact but accurate HSPICE macromodel for singlebit resistive RAM (ReRAM) is proposed in this paper. This compact macromodel uses the minimum number of circuit elements to improve the HSPICE simulation speed. And, the macromodel is verified to show very good agreement with the measurements due to voltagecontrolled resistors used as the SET and RESET resistors in the macromodel describing wel...

Charge transport in nanosized electronic systems is described by semiclassical or quantum kinetic equations that are often costly to solve numerically and difficult to reduce systematically to macroscopic balance equations for densities, currents, temperatures and other moments of macroscopic variables. The maximum entropy principle can be used to close the system of equations for the moments b...

Information technology has made experimenting via the internet possible. Different from simulations, applets or animations, remotely controlled experiments give students the possibility to experience in reality physical situations and the realistic response to parameter variations. We demonstrate how to measure the efficiency of a solar cell by recording the IV curve in the dark and under illum...

Experimental results on the electrical characteristics of Hg-alkanethiol/arenethiol-Au molecular junctions are used to develop a physical model for the hysteretic negative-differential resistance NDR for these, and possibly other, metal-molecule-metal junctions. The dependence of the room-temperature current-voltage characteristic on sweep direction and sweep rate is examined. Based on several ...

Abstract. Organic diodes and solar cells are constructed by placing together two organic semiconducting materials with dissimilar electron affinities and ionisation potentials. The electrical behaviour of such devices has been successfully modeled numerically using conventional drift diffusion together with recombination (which is usually assumed to be bimolecular) and thermal generation. Here ...

• The architecture of chaos oscillator should be similar to classical second order sine wave oscillator, e.g. LC or Wien-bridge based circuit. • The oscillator should not be higher than the third order system. • The circuit should be an autonomous oscillator. • The active unit should be linear and separated from the nonlinear element(s). • The nonlinear element should be single and simple, e.g....

In this paper a model of the quasineutral plasma and the transition between the plasma and the dielectric wall in a Hall thruster channel is developed. The plasma is considered using a two-dimensional hydrodynamic approximation while the sheath in front of the dielectric surface is considered to be one dimensional and collisionless. The dielectric wall effect is taken into account by introducin...

Typical blocking I–V characteristics are shown and analyzed for PN junctions exhibiting a breakdown region above 1000 V from commercial diodes and power MOSFETs. The leakage reverse current of PN junctions from commercial silicon devices available at this time has a flowing component at the semiconductor–passivant material interface around the junction edge. Part of the plotted experimental cur...
