In this paper, we propose a method based on genetic algorithms to extract primary lightning return stroke current parameters from currents measured using instrumented towers, including the possibility of contamination by multiple reflections occuring along ...
Thin films of neodymium-modified bismuth titanate Bi3.44Nd0.56Ti3O12 (BNT) were grown on Pt/TiO2/SiO2/Si substrates using chemical solution deposition method. The capacitors made by applying top Au electrodes on BNT films showed significantly improved valu ...
Different FEM formulations have been developed in order to model the electromagnetic behaviour of type II super-conductors. The paper presents a comparison between simulations with A-V formulation models implemented in two FEM software packages (FLUX2D and ...
Temperature and electric field dependencies of mobility and concentration transients of electrons and holes using modified charge extraction by the linearly increasing voltage (CELIV) method in slightly doped n-type, p-type and undoped microcrystalline sil ...
The electrochem. oxidn. of phenol at synthetic boron-doped diamond thin film electrode (BDD) was studied in acid media by cyclic voltammetry, chronoamperometry, and bulk electrolysis. In the potential region of water stability (E
In microcrystalline hydrogenated silicon (μc-Si:H), the drift mobility dependencies of holes on electric field and temperature have been measured by using a method of equilibrium charge extraction by linearly increasing voltage. At room temperature the est ...
Two methods for the estn. of the current bypass in solid state electrochem. are presented. The current bypass was estd. from the current-voltage curves of a tubular cell with one bipolar element and from the current-voltage curves of a monolith with severa ...
A digital lock-in amplifier has been used to perform V-I time series acquisition when transport currents with amplitude above Ic are driven through Bi-2223 tapes. The current waveform is triangular, sinusoidal or with arbitrary shape, and is applied for se ...
Leakage conduction of Pt-Pb(ZrXTi:(1-X))O-3-Pt capacitors is studied by means of different measuring techniques and analyzed in terms of semiconductor properties of the system. Based on the experimental data, it is concluded that two different regimes of c ...
We propose a new configuration for semiconductor optical amplifiers (SOAs), called optical speed-up at transparency (OSAT), which allows to speed up the gain recovery of SOAs and their saturation power without sacrificing the gain, nor increasing the appli ...
