Electrical characteristics of single and multiple point defects in a photonic crystal waveguide are investigated. It is shown that a single defect can be inductive or capacitive. A double defect behaves as a bandpass filter.
We report on the fabrication and electrical characterization of Ω-gated nanowire (NW) array pFETs on SOI. Devices with gate lengths of L = 400nm and L = 2 μm and 〈110〉 - and 〈100〉 - channel orientations were fabricated using a top-down approach. Each device consists of up to 1500 NWs with a crosssection of 20 × 20 nm2. The devices feature excellent electrical characteristics with high on-currents,...
We study the electromagnetic behavior and the characteristics of dielectric mixtures. The effective permittivity of non-homogenous mixtures is very important in order to design composites materials with specific electrical characteristics. Simulation results show the distribution of the electric field E and the electric displacement D for ordered mixtures and for those with random distribution of...
2D simulation of dark current and photoresponse for InP/InGaAs/InP photodiode is carried out by Sentaurus DEVICE. The simulation results are in good agreement with experiments confirming that generation-recombination effect is the dominant source of dark current at low bias.
Results of numerical optimization of electrical characteristics and geometry of ultra wideband double ridged horn antennas are presented.

This paper reports the assessment results of 96 fractional and small power three phase induction motors for roller and conveyor in-plant transportation applications. The motors have a number of poles from 2 up to 12 and they have been selected in order to get a significant sample of the induction motors used in conveyor and roller systems. An indirect method has been used for the determination of...
High quality ZnO films were obtained by thermal oxidation of Zn films on the temperature range from 300 to 700 °C. Zn films of 190 nm in thickness were deposited on silicon and glass substrates by the sputtering technique. Thermal oxidation was done at normal environment conditions. The complete oxidation of the Zn films was determined by the ZnO films transparency. The ZnO films resulted dense with...
This paper presents a wafer-level microwave multichip module (MMCM) packaging process for 24GHz driver amplifier using photosensitive-Benzocyclobutene (photo-BCB) of 25 μm. It is developed for multilayer interconnection of monolithic microwave integrated chip (MMIC). A 24 GHz driver amplifier chip is embedded in a wet-etched trench on 4 inch lossy Si wafer and covered with a layer of BCB as dielectrics...
In this paper, we have simulated the different technology node FinFET devices and its electrical characteristics variation especially short channel effects (SCE). Raised source and drain (RSD) structure for parasitic resistance minimization with ultra thin undoped fin are used. This RSD reduces the series resistance without affecting SCEs in terms of drain induced barrier lowering (DIBL), subthreshold...

We show the behavior of the generations of two multi-objective evolutionary algorithms (MOEAs) for the optimal sizing of two mixed-mode circuits. The non-sorting genetic algorithm (NSGA-II), and the MOEA based on decomposition (MOEA/D) are used to size a second generation current conveyor (CCII+) and a current-feedback operational amplifier (CFOA). Both MOEAs take into account design constraints,...
We present the perspective of CMOS electronics as a candidate for the readout purposes of sensing devices such as the Single Electron Transistor (SET) at very low temperature. Fully Depleted Silicon on Insulator (FD-SOI) CMOS devices are less susceptible to low temperature anomalies compared to bulk devices. The electrical characteristics of a typical SET are too small in comparison to usual current/voltage...
Electrical characteristics of nano-crystalline silicon (nc-Si) thin-film transistors (TFTs) are fit using SPICE device models. The corresponding device model geometry is then extrapolated down to submicron dimensions using electrical data measured on a-Si:H transistors as justification. The nanoscale devices are then used to simulate a spiking neuron circuit. The frequency of output voltage pulses...
SOI FinFET transistors have emerged as novel devices having superior controls over short channel effects (SCE) than the conventional MOS transistor devices. However despite these advantages, these also exhibit certain other undesirable characteristics such as corner effects, quantum effects, tunneling etc. Usually, the corner effect deteriorates the performance by increasing the leakage current. In...
In this paper the effect on dc and ac electrical properties of silica nano and micro particles dispersed in epoxy resins is discussed. In particular, space charge, conductivity, dielectric strength and partial discharge resistance is analyzed. The results show that nanostructured materials exhibit smaller space charge accumulation with respect to both base and microfilled materials. Regarding PD resistance,...
Epoxy resin is widely used in high voltage apparatus as insulation. Fillers are often added to epoxy resin to enhance its mechanical, thermal and chemical properties. The addition of fillers can deteriorate electrical performance. With the new development in nanotechnology, it has been widely anticipated that the combination of nanoparticles with traditional resin systems may create nanocomposite...

Wireless power transfer is essential for the spread of Electric Vehicle(EV) usage as it provides a safe and convenient way to charge the EVs. Recently, a highly efficient mid-range wireless power transfer technology using electromagnetic resonance coupling, WiTricity, was proposed. Studies show that the resonant frequencies of the two antennas change according to the air gap in between the antennas...
