Tungsten trioxide (WO3) thin films with Pt and Cu electrodes are characterized regarding the suitability for nonvolatile memory applications. Cells down to 70 ?? 70 nm2 are fabricated by a combination of e-beam and nanoimprint lithography. The electrical measurements reveal good properties with switching currents of only 500 nA, fast SET and RESET switching down to 5 ns and retention for 104 s with...
The water displacing oil physical simulation system and modeling method based on radial basic function network is presented in this paper. The 512 routes strobe circuit and the constant current source which can adjust the range intelligently are designed in this simulation system. According to the approximate linear relationship between the resistance rate value and the water saturation, the resistivity...
LSMO thin films materials have a strong interaction between their electrical and magnetic properties that could be translated into innovative tunable components. The knowledge of the electroactive and magnetoactive properties of these materials is essential for modeling and design of their novel based- devices. The activity of these materials can be described by their electro/magento resistance and...
A table-based nonlinear approach was used to predict the performance of a commercially packaged Schottky diode. Excellent results have been obtained which improve those of the analytical model provided by the manufacturer. Both models were extensively validated under DC, small and large-signal one-tone and two-tone excitations. Measurements for table-based model extraction and models validation were...
A high power pHEMT with longer drain-gate separation can operate at higher voltage. However, it shows large output power loss at millimeter-wave in addition to the conventional parasitic power dissipation. The nonlinear drain resistance Rd of the pHEMT is found to cause the large power loss, although it behaves as a conventional resistor at low frequency. The nonlinearity of the Rd is modeled and...
Existing schemespsila characteristics to measure capacitive current are analyzed, in order to measure capacitive current of distribution network in formidable conditions of coal mine. The new measurement scheme of capacitive current is put forward, which is based on a resistant added single-Phase line. Using this new method, the capacitive current of single-phase ground fault is predicted through...
