Reduction of the Superconducting Gap of Ultrathin Pb Islands Grown on Si(111)

Wolf-Dieter Schneider, François Patthey, I-Po Hong

The energy gap Delta of superconducting Pb islands grown on Si(111) was probed in situ between 5 and 60 monolayers by low-temperature scanning tunneling spectroscopy. Delta was found to decrease from its bulk value as a function of inverse island thickness ...

In-Situ vs. Ex-Situ Nanocrystallization of Mn-Doped ZnO

László Forró, Arnaud Magrez, Duncan Thomas Lindsay Alexander, Zlatko Mickovic

Following the current interest in transition metal doped dielectrics for spintronic applications, Mn-doped ZnO is being made by thermal decomposition of Mn-doped hydrozincite,  (MnxZn1–x)5(OH)6–2n (CO3)1+n, precursors that have been prepared by a novel syn ...

Microfabricated Dual Sprayer for On-Line Mass Tagging of Phosphopeptides

Hubert Girault, Niels Erik Lion, Michel Prudent, Joël Stéphane Rossier

Phosphopeptides tagging reactions by dinuclear zinc(II) complexes (1,3-bis[bis(2-pyridylmethyl)amino]-propan- 2-olato dizinc(II)3+, called tag) were performed with a dual-channel microsprayer in electrospray ionization mass spectrometry. The reaction is fi ...

Mechanical integrity analysis of multilayer insulator coatings on flexible steel substrates

Yves Leterrier

The cohesive and adhesive properties, and related critical radius of curvature of thin multilayer insulator coatings on a 152 μm thick flexible steel substrate were investigated using tensile experiments carried out in-situ in an optical microscope. This m ...

Precipitation of Nanostructured Copper Oxalate: Substructure and Growth Mechanism

Heinrich Hofmann, Paul Bowen, Jacques Lemaître, Lucica Soare

The possibility of controlling materials properties by tailoring their substructure at the nanometer scale is a current topic of great interest. To do so, a fundamental understanding of the growth mechanism is of key importance and an analytical challenge ...

In situ micro gripper shaping by electro discharge machining

Reymond Clavel, Mélanie Dafflon, Cédric Joseph

A machining process based on Electro Discharge Machining (EDM) has been developed and allows producing flexible and low-cost tweezers-like grippers or grippers shaped for a specific application. It can be easily included in a micromanipulation setup and re ...

The role of the amino-organosilane/SiOx interphase in the barrier and mechanical performance of nanocomposites

Yves Leterrier, Gil Rochat

The aim of this study is to develop coatings on polymer substrates with a combined increase in oxygen barrier performance and toughness, based on SiOx coatings modified with multifunctional organo-silane polymers of controlled polarity and reactivity. As a ...

IN-SITU STABILIZATION OF MEMBRANES FOR IMPROVED LARGE-AREA AND HIGH-DENSITY NANOSTENCIL LITHOGRAPHY

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. Currently, large area pattern transfer using nanostencil lithography is ...

Laser microspot welding of copper

René Salathé, Thomas Sidler, Simone Amorosi

A new procedure for laser spot welding of thin copper stripes was developed based on measuring the calibrated reflectivity coaxially to the laser beam and using this signal for in situ control of the laser power. Experiments with a power ramp of r=3.1 MW/s ...
