Transition between grain boundary and intragrain scattering transport mechanisms in boron-doped zinc oxide thin films

A comprehensive model for the electronic transport in polycrystalline ZnO:B thin films grown by low pressure chemical vapor deposition is presented. The optical mobilities and carrier concentration calculated from reflectance spectra using the Drude model ...

LONG LIFETIME SYSTEM FOR THE GENERATION OF SURFACE PLASMAS

Pénélope Leyland

The invention concerns a system of electrodes for generating a surface dielectric barrier discharge totally encapsulated in a ceramic dielectric, using co-fireable ceramic technology (ceramic tapes, LTCC, HTCC, green tapes). The plasma generation device ca ...

Polylactic Acid–Phosphate Glass Composite Foams as Scaffolds for Bone Tissue Engineering

Dominique Pioletti, Pierre-Etienne Bourban

Phosphate glass (PG) of the composition 0.46(CaO)–0.04(Na2O)–0.5(P2O5) was used as filler in poly-L-lactic acid (PLA) foams developed as degradable scaffolds for bone tissue engineering. The effect of PG on PLA was assessed both in bulk and porous composit ...

LTCC thermal gas viscometer – heater module

Peter Ryser, Thomas Maeder, Caroline Jacq, Hansu Birol, Giancarlo Corradini

In this work, a novel sensor for measuring the viscosity of a gas, based on the combination of a heating cavity, a pressure sensor and a meander with a high resistance to flow, all integrated in low-temperature co-fired ceramic (LTCC) technology, is presen ...

Preparation and Characterization of (K0.5, Na0.5)NbO3

Nava Setter, Dragan Damjanovic, Hansu Birol

In this paper the preparation and characterization of the ceramic material (K0.5Na0.5)NbO3 (KNN) has been studied. Although conventional processing of KNN is often reported to result in sintered bodies lacking sufficient density, samples produced in this w ...

Development and validation of a Radiance model for a translucent panel

Marilyne Andersen

Abstract This study describes the development and validation of a Radiance model for a translucent panel. Using goniophotometer data combined with integrating sphere measurements, optical properties of the panel were derived and converted into a Radiance m ...

High-Voltage Sensitivity Studies of Model Thick-Film Resistors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Niklaus Johner, Adrian Kambli

In this work we seek to better understand the mechanisms governing pulse voltage trimming in disordered conductor-insulator composites. Therefore, we investigate the effect of the composition of thick-film resistors (TFRs) on sensitivity to high voltage pu ...

MICRO-MOULDING OF CERAMIC STRUCTURES USING CERAMIC-PRECURSOR POLYMERS

Jürgen Brugger, Vahid Fakhfouri

We develop ceramic structures using ceramic-precursor polymers. The possibility to modify easily the physical properties of the final ceramic structures just by doping the precursor with nanoparticles, makes them interesting for new MEMS and NEMS developme ...

Development of low-temperature thick-film materials for piezoresistive sensors

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

Thick-film materials are very advantageous for piezoresistive pressure and force sensors because of ease of processing, reliability and low cost. However, their applications are restricted because standard thick-film materials require processing temperatur ...
