LTCC (low temperature co-fired ceramic) technology has recently gained a remarkable application potential in sensors field. This can be ascribed to many advantages it offers: the ease of LTCC tape handling providing a great freedom in design and fabricatio ...
Scanning electrochemical microscopy (SECM) was used to characterize addressable microelectrode arrays patterned with 25 regularly spaced (100 μm center to center) 10 μm diameter platinum microdisks. Both the feedback mode and the substrate generation/tip c ...
GaN/AlN quantum-dot superlattices grown by molecular-beam epitaxy on silicon (111) or sapphire (0001) substrate have been investigated using high-resolution transmission electron microscopy, photoluminescence, and photo-induced absorption spectroscopy. Und ...
Abstract In this paper we present our latest developments in high precision positioning and handling systems operating inside Scanning Electron Microscopes (SEM). This work is motivated by the growing need of new instruments for the in-situ analysis of mat ...
In spite of many advantages it offers for micro-electronic packaging, the low temperature co-fired ceramic (LTCC) technology has yet certain issues to be solved. Physical and chemical reactions, for instance, within and between the passive electronic compo ...
Microorganisms were searched for among the complex microstructures observed on the surface of a fragment of the Tatahouine meteorite inherited from the Tunisian soil in which they were buried. In this view, the chemical compositions, particularly the nitro ...
A novel C-Nafton/Fe-ion structured fabric capable of mediating Orange II decomposition in Fenton-immobilized photoassisted reactions is presented. The catalyst preparation requires the right balance between the amount of the Nafion necessary to protect the ...
We investigate both theoretically and experimentally the effects of the In surface segregation in InGaN/GaN quantum wells (QWs). It is shown that this phenomenon induces a blue-shift of the QW photoluminescence (PL) energy, which does not depend on the QW ...
Quantitative analysis of high resolution electron microscopy image has been carried out to measure the indium distribution inside InGaN/GaN quantum well. The analyzed samples were nominally grown with 15% indium composition by molecular beam epitaxy with i ...
A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. Th ...
