The relaxation current decays with time t to follow the Curie-von Schweidler law of Jr(t) = J0t-n with the exponent n slightly less than the unity either under or after dc-voltage stressing of Pb(Zr,Ti)O3 thin films, in agreement with direct measurements of capacitance dispersion evaluated from frequency spectrum. J 0 versus voltage shows a typical behavior of p-n junction at t = 0.28 s but overlapping of twin p-n junctions at t
The vertical DMOS (Double Diffused MOSFET) is widely used in power microelectronics, its switching performance is determined mainly by the gate resistance and the input capacitance. Thus a gate resistance testing tech...

In this paper,we study a novel chemical gas sensor arrays based on polymer-carbon black *** two different polymers which are poly(4-vinyl phenol), poly(ethylene oxide) are employed as the sensor materials which are immobilized on the array of the interdigitaled microelectrode *** resistance change of sensors of two different organic gases (toluene,methanol) at different concentration has been examined(300ppm,600ppm,900ppm,1200ppm, 1500ppm).At low concentration,Langmuir absorption model is used to explain the reason of the resistance *** relationship between the resistance changes and gas concentration in the range from 300ppm to 1500ppm can be approximated to a straight line;the chemical absorption is also existed in the absorption.
The design of acoustic resonator is critical for the sensitivity of photoacoustic (PA) gas detection. In this paper, a LC Circuit model is built for the simulation of ID acoustic resonator with considerations of some ...
