A study of polarization effects in metal-ferroelectric-oxide-semiconductor capacitors

Mihai Adrian Ionescu, Giovanni Antonio Salvatore, Alexandru Rusu

In this paper we report the fabrication and detailed electrical characterization of a Metal-Ferroelectric-Oxide-Semiconductor Capacitor aiming at the extraction of the polarization characteristic. In order to evaluate the electrical performances of the fer ...

Micro-electro-mechanical (MEM) diode switch

Mihai Adrian Ionescu, Didier Bouvet, Dimitrios Tsamados, Donatello Acquaviva

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 ...

Polarisation reversal in ferroelectric PVDF and PZT films

Roman Gysel

Ferroelectrics are characterised by a spontaneous polarisation that can be reversed by an external electric field. The stability of the polarisation states and the possibility for controlled switching between the states render ferroelectric materials very ...

Reliability study of tunable ferroelectric capacitors

Nava Setter, Marija Kosec

In this paper, the reliability of tunable ferroelectric thin film capacitors has been addressed. The long term stability of tunable capacitors based on Ba0.3Sr0.7TiO3 films deposited by chemical solution deposition onto an alumina substrate was investigate ...

An adaptive model of overheating risk

Darren Robinson, Frédéric Haldi

Based on analogy between the charging and discharging of humans' tolerance to overheating stimuli and that of charge in an electrical capacitor, this paper proposes a simple mathematical model for predicting overheating risk given a set of measured / simul ...

Introducing the Common Cross Connected Stage (C3S) for the 5L ANPC Multilevel Inverter

Alfred Rufer

This paper proposes a novel multilevel Power Electronics Building Block (PEBB) for the 5 level ANPC multilevel voltage source inverter [7]. The PEBB is composed of 6 switches in a crossed configuration [8] and one capacitor. It is common to the 3 phases of ...

Model to predict overheating risk based on an electrical capacitor analogy

Darren Robinson, Frédéric Haldi

It is important for building designers to be able to judge if a space is likely to overheat, whether to determine if HVAC plant is required or to design this out by passive means. To this end several overheating risk criteria have recently been published. ...

Fibronectin adsorption on tantalum: The influence of nanoroughness

Kristian Rechendorff

The complex mechanisms of protein adsorption at the solid-liquid interface is of great importance in many research areas, including protein purification, biocompatibility of medical implants, biosensing, and biofouling. The protein adsorption process depen ...

An Integrated Adaptive Model for Overheating Risk Prediction

Darren Robinson, Frédéric Haldi

Based on results from a field survey campaign, this paper describes three new developments which have been integrated to provide for a comprehensive basis for the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations ha ...
