Extraction of the spin torque non-adiabaticity from thermally activated domain wall hopping

We investigate the non-adiabaticity of current-induced domain wall motion by time resolved analysis of thermally activated domain wall motion between two metastable states within a Co/Pt multilayer wire with a strong uniaxial perpendicular anisotropy. By m ...

Aqueous solution self-assembly of polystyrene-b-poly(L-lysine) diblock oligomers

Harm-Anton Klok, Harald Nuhn

This paper reports on the dilute, aqueous solution self-assembly of two asymmetric polystyrene-b-poly(L-lysine) (PSnPKm) diblock oligomers with PS and PK number-average degrees of polymerization of eight, respectively, 40 and 60. The self-assembly of these ...

Hyperbranched Anatase TiO2 Nanocrystals: Nonaqueous Synthesis, Growth Mechanism, and Exploitation in Dye-Sensitized Solar Cells

Raffaella Buonsanti

A colloidal crystal-splitting growth regime was used in which TiO2 nanocrystals, selectively trapped in the metastable anatase phase, can evolve to anisotropic shapes with tunable hyper-branched topologies over a broad size interval. The synthetic strategy ...

Holographic second harmonic generation (SHG) microscopy

Christian Depeursinge, Pierre Marquet, Etienne Shaffer

The coherent nature of second harmonic generation (SHG) makes possible retrieval of both its amplitude and its phase, by use of a proper phase-sensitive imaging technique such as digital holographic SHG microscopy. In addition to retrieving both amplitude ...

Supersolid Phase with Cold Polar Molecules on a Triangular Lattice

Jean-David Picon

We study a system of heteronuclear molecules on a triangular lattice and analyze the potential of this system for the experimental realization of a supersolid phase. The ground state phase diagram contains superfluid, solid, and supersolid phases. At finit ...

Ultraviolet Photodetectors Based on Anodic TiO2 Nanotube Arrays

Nicola Marzari, Ke Huang

Anodic TiO2 nanotube arrays prepared by electrochemical anodization were used to fabricate ultraviolet (UV) photodetectors. The devices annealed at 450 degrees C exhibit the highest UV-sensitive photoconductance due to the pure anatase phase of the TiO2. T ...

High-pressure study of anatase TiO2

László Forró, Arnaud Magrez, Richard Gaal, Helmuth Berger, Jacim Jacimovic, George Cristian Vaju

We report resistivity and thermo-electric power measurements of the anatase phase of TiO2 under pressure up to 2.3 GPa. Despite its transparent appearance, the single crystal of anatase exhibits a metallic-like resistivity above 60 K, at all pressures. The ...

Sensors and packages based on LTCC and thick-film technology for severe conditions

Peter Ryser, Thomas Maeder, Caroline Jacq

Reliable operation in harsh environments such as high temperatures, high pressures, aggressive media and space, poses special requirements for sensors and packages, which usually cannot be met using polymer-based technologies. Ceramic technologies, especia ...

A theoretical study of disorder and decomposition in multinary nitrides hard coatings materials

Björn Alling

The development of multinary nitrides materials has revolutionised the hard coatings industry over the last 20 years. Especially important materials systems in this matter have been TiAlN and CrAlN which shows higher hardness, better oxidation resistance a ...
