Study of the Optical UV-Visible Electron Induced Luminescence of Small Size Selected Metal Clusters in Rare Gas Solids

The optical properties of small size selected metal clusters have been studied by fluorescence spectroscopy. Cun (n = 1-5, 8), Agn (n = 1-5, 8, 9, 20), Aun (n = 1-5, 8) and Nin (n = 1-3) clusters embedded in condensed neon are photoionized by VUV photons i ...

Inelastic electron tunneling spectroscopy: A route to the identification of the tip-apex structure

Klaus Kern

The vibrational spectrum of a tunneling junction on a clean Cu(111) surface has been characterized by vibrational density of states calculations and inelastic electron tunneling spectroscopy technique. We demonstrate that the achieved spectrum consists not ...

Solution of the tunneling-percolation problem in the nanocomposite regime

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Gianluca Ambrosetti

We noted that the tunneling-percolation framework is quite well understood at the extreme cases of percolation-like and hopping-like behaviors but that the intermediate regime has not been previously discussed, in spite of its relevance to the intensively ...

Gyrokinetic Simulations of Microturbulence in TCV Electron Internal Transport Barriers

Olivier Sauter, Laurent Villard, Stephan Brunner, Xavier Lapillonne

Using the Eulerian code GENE [1], gyrokinetic simulations of microturbulence were carried out under conditions relevant to electron-Internal Transport Barriers (eITB) in the TCV tokmak [2], generated under conditions of low or negative shear. For typical d ...

Comparative Dissociation of Peptide Polyanions by Electron Impact and Photo-Induced Electron Detachment

Yury Tsybin, Aleksey Vorobyev, Rodolphe Antoine

We compare product-ion mass spectra produced by electron detachment dissociation (EDD) and electron photodetachment dissociation (EPD) of multi-deprotonated peptides on a Fourier transform and a linear ion trap mass spectrometer, respectively. Both methods ...

Analysis of cubic and orthorhombic C(3)A hydration in presence of gypsum and lime

Field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) have been used to study the microstructural changes and phase development that take place during the hydration of cubic (pure) and orthorhombic (Na-doped) tricalcium aluminate ...

High-Quality 2D Metal−Organic Coordination Network Providing Giant Cavities within Mesoscale Domains

Harald Brune, Uta Schlickum, Régis Decker

A surface-supported open metal−organic nanomesh featuring a 24 nm2 cavity size and extending to μm domains was fabricated by Co-directed assembly of para-hexaphenyl-dicarbonitrile linker molecules in two dimensions. The metallosupramolecular lattice is the ...

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 ...

Plasmon enhanced luminescence from fullerene molecules excited by local electron tunneling

Wolf-Dieter Schneider, François Patthey, Marina Pivetta, Frédéric Rossel

Tunneling electrons from a scanning tunneling microscope (STM) induce luminescence from C-60 and C-70 molecules forming fullerene nanocrystals grown on ultrathin NaCl films on Au(111). Intramolecular. uorescence and phosphorescence associated with the tran ...
