Metal/GaN reaction chemistry and their electrical properties

We investigated the reaction chemistry of metal contacts to GaN during annealing using X-ray photoelectron spectroscopy (XPS). GaN decomposition was estimated, using XPS, to occur in N-2 annealed Ni-alloy contacts at 550 degreesC. The reaction was greatly ...

Piezoresistive anisotropy of thick-film resistors

Peter Ryser, Claudio Grimaldi

Numerous evidence suggests that thick-film resistors are close to a metal– insulator transition and that tunneling processes between metallic grains are the main source of resistance. By theoretical analysis of various percolative resistor network models w ...

Speciation of zinc in municipal solid waste incineration fly ash after heat treatment: An X-ray absorption spectroscopy study

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis

Fly ash is commonly deposited in special landfills as it contains toxic concentrations of heavy metals, such as Zn, Pb, Cd, and Cu. This study was inspired by our efforts to detoxify fly ash from municipal solid waste incineration by thermal treatment to p ...

Impact of moisture on volatility of heavy metals in municipal solid waste incinerated in a laboratory scale simulated incinerator

Christian Ludwig

In this work, the impact of moisture on the volatility of heavy metals present in municipal solid wastes (MSW) in a laboratory scale simulated incinerator was studied, using synthetic waste consisting of 5.4 g of wood powder, 2.6 g lava, 1.9 polythene, 0.1 ...

The effect of boundary conditions and sample aspect ratio on apparent d(33) piezoelectric coefficient determined by direct quasistatic method

Nava Setter, Dragan Damjanovic

The effect of boundary conditions (e.g., type of metal contacts) and sample geometry (e.g., sample aspect ratio) on measurements of direct longitudinal d(33) coefficient in piezoelectric ceramics is studied by direct quasistatic method. We show that at sma ...

Test results on the first 50 kA NbTi full size sample for the International Thermonuclear Experimental Reactor

Boris Stepanov

Within the framework of the R&D studies for the International Thermonuclear Experimental Reactor (ITER) project, the first full size NbTi conductor sample was fabricated industrially and tested in the SULTAN facility (Villigen, Switzerland). This sample (P ...

Process for avoiding cracking in welding

Michel Rappaz, Wilfried Kurz, Jean-Daniel Wagnière

The new welding process avoids cracking in welding, in repair welding or in cladding of parts of metallic alloys which are sensitive to hot cracking. The process is using a first heat source (15), directed to the parts (11, 12) of the metallic alloy formin ...

Piezoresistivity and conductance anisotropy of tunneling-percolating systems

Peter Ryser, Claudio Grimaldi, Thomas Maeder

We propose a theory of the origin of transport nonuniversality in disordered insulating-conducting compounds based on the interplay between microstructure and tunneling processes between metallic grains dispersed in the insulating host. We show that if the ...
