Fabrication of CMOS-compatible abrupt electronic switches based on vanadium dioxide

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Wolfgang Amadeus Vitale, Antonio Paone

Vanadium dioxide thin films were deposited on amorphous SiO2-coated Si substrates, by reactive magnetron sputtering at 490 °C of a pure vanadium target. The deposition parameters were optimized in order to maximize the resistivity modulation due to the met ...

Chiral Cyclopentadienyl Iridium(III) Complexes Promote Enantioselective Cycloisomerizations Giving Fused Cyclopropanes

Nicolai Cramer, Yun-Suk Jang, Michael Christian Dieckmann

The cyclopentadienyl (Cp) group is a very important ligand for many transition-metal complexes which have been applied in catalysis. The availability of chiral cyclopentadienyl ligands (Cp-x) lags behind other ligand classes, thus hampering the investigati ...

Influence of doping in thermochromic V1−xWxO2 and V1−xAlxO2 thin films: Twice improved doping efficiency in V1−xWxO2

Jean-Louis Scartezzini, Andreas Schueler, Rosendo Sanjines, Antonio Paone

The parameters of thermal evaporation and magnetron sputtering deposition were optimized for fabrication of vanadium dioxide thin films. The O2 partial pressure during film deposition is critical for obtaining a pure VO2 phase. Thermochromic V1−xWxO2 (x = ...

Hydrogen plasma treatment for improved conductivity in amorphous aluminum doped zinc tin oxide thin films

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Sylvain Nicolay, Monica Morales Masis, Laura Ding, Fabien Paul Jacques Dauzou

Improving the conductivity of earth-abundant transparent conductive oxides (TCOs) remains an important challenge that will facilitate the replacement of indium-based TCOs. Here, we show that a hydrogen (H-2)-plasma post-deposition treatment improves the co ...

Dynamic nuclear polarization enhancement of protons and vanadium-51 in the presence of pH-Dependent vanadyl radicals

Geoffrey Bodenhausen, Andrzej Sienkiewicz, Pascal Miéville, Diego Carnevale, Angel Joaquin Perez Linde

© 2014 John Wiley & Sons, Ltd. We report applications of dynamic nuclear polarization to enhance proton and vanadium-51 polarization of vanadyl sulfate samples dopedwith TOTAPOL undermagic angle spinning conditions. The electron paramagnetic resonance resp ...

Preparation and Characterization of High-Surface-Area Bi(1-x)/3V1-xMoxO4 Catalysts

Lioubov Kiwi, Alexandre Nell

We report the successful application of a templating approach employing ordered mesoporous carbon to the synthesis of BiVO4, Bi2Mo3O12, and Bi0.85V0.55Mo0.45O4 and the performance of these materials as catalysts for the oxidation of propene to acrolein. Or ...

Direct determination of niobium at the low nanogram level in mineral waters and freshwaters

Michaël Bensimon, Montserrat Filella, David-Julien Magnenat

The increasing use of elements such as Nb and Ta in green and information technologies makes it necessary to develop appropriate analytical methods for studying their environmental and ecotoxicological behaviour. This paper describes the first time Nb has ...

Evaluation of niobium dimethylamino-ethoxide for chemical vapour deposition of niobium oxide thin films

Patrik Willi Hoffmann, Ali Dabirian, Yury Kuzminykh, Estelle Wagner, Giacomo Benvenuti

Chemical vapour deposition (CVD) processes depend on the availability of suitable precursors. Precursors that deliver a stable vapour pressure are favourable in classical CVD processes, as they ensure process reproducibility. In high vacuum CVD (HV-CVD) pr ...

Annealing effects on the microstructure and photoluminescence of Eu3+-doped GdVO4 powders

Barbora Bártová

This work explores the influence of annealing temperature on microstructure and optical characteristics of Eu3+ doped GdVO4 (0.5, 1, 2 and 3 at.% Eu3+) nanopowders produced via co-precipitation synthesis. Samples were annealed at different temperatures (30 ...
