The TORCH time-of-flight detector

Christoph Frei

The TORCH time-of-flight detector is being developed to provide particle identification between 2 and 10 GeV/c momentum over a flight distance of 10 m. TORCH is designed for large-area coverage, up to 30 m(2), and has a DIRC-like construction. The goal is ...

Combinatorial HV-CVD survey of barium triisopropyl cyclopentadienyl and titanium tetraisopropoxide for the deposition of BaTiO3

Patrik Willi Hoffmann, Yury Kuzminykh, Michael Oliver Reinke

Barium titanate is a very promising material for the integration of optical communication into electronic integrated circuits. For a successful integration into CMOS compatible technology, a growth process has to be found which allows forming crystalline B ...

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 = ...

Facile route to freestanding CH3NH3PbI3 crystals using inverse solubility

Michael Graetzel, Ulf Anders Hagfeldt, Kazuteru Nonomura, Jeannette Medina Kadro

CH3NH3PbI3 was found to exhibit inverse solubility at high temperatures in gamma-butyrolactone. Making use of this unusual, so far unreported phenomenon, we present a facile method for the growth of freestanding crystals of CH3NH3PbI3 from solution without ...

Increasing Polycrystalline Zinc Oxide Grain Size by Control of Film Preferential Orientation

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Monica Morales Masis, Lorenzo Fanni, Arthur Brian Aebersold

We investigate the structural evolution of polycrystalline zinc oxide films grown by low pressure metal-organic chemical vapor deposition. The goal is to achieve larger grains-leading to higher charge carrier mobility from lower grain boundary density-by c ...

Hydrothermal Synthesis of SrTiO3: Role of Interfaces

Andrea Testino, Agnese Carino, Paolo Nanni

The hydrothermal synthesis of SrTiO3 in a Sr(OH)(2)/NaOH solution by reaction of four different single crystalline titanium precursors (anatase, rutile, sodium titanate, and hydrogen titanate) having the same nanowire morphology was investigated under stag ...
