We present piezoresponse force microscopy measurements on individual integrated potassium niobate (KNbO3) nanowires. The devices consist of KNbO3 nanowires on SiO2 substrates being mechanically clamped and electrically biased by lithographically defined me ...
A memory capacitor with a multistacked tunnel layer of Al2O3/HfO2/SiO2 (AHO) has been fabricated together with HfO2 charge trapping layer and Al2O3 control oxide layer. The resulting capacitor exhibits a memory window as large as 7.6 V for +/- 12 V sweep v ...
Based on results from a field survey campaign, this paper describes three new developments which have been integrated to provide for a comprehensive basis l'or the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations h ...

We formulate an approach to the size effect problem in ferroelectric-electrode systems where ab initio calculations are combined with a phenomenological framework. The parameters of the model can be extracted from the calculations, while experimentally ver ...

This paper presents a programmable multi-mode finite impulse response (FIR) filter implemented as switched capacitor (SC) technique in CMOS 0.18 μm technology. Intended application of the described circuit is in analog base-band filtering in GSM/WCDMA syst ...
The design, fabrication and characterization of Micro-electro-mechanical metal-air-insulator-semiconductor (MEM-MAIS) diode switch are originally reported. An abrupt switching from off-state to Fowler-Nordheim tunneling current in on-state is induced by th ...
The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectly for ...

A simple approach to the realisation of a differential Colpitts oscillator is to connect the grounded capacitor in the feedback network of two single-ended Colpitts oscillators together in series. As the output signals are expected to be differential, it i ...
