Experimental and numerical study of microstructure formation and the origin of crystallographic misorientation in Al-Zn-Si alloy coatings

Al-Zn-Si alloy coatings are widely used for the corrosion protection of steel sheets. In addition to the favorable corrosion properties, the Al-43wt%Zn-1.6wt%Si coatings present several features which are of metallurgical interest. The first one is their s ...

Terahertz photonic crystal quantum cascade lasers

Romuald Houdré, Hua Zhang, Jérôme Faist

We combine photonic crystal and quantum cascade band engineering to create an in-plane laser at terahertz frequency. We demonstrate that such photonic crystal lasers strongly improve the performances of terahertz quantum cascade material in terms of thresh ...

Spin resonance in the ordered magnetic state of Ni-5(TeO3)(4)Cl-2

László Forró, Helmuth Berger, Bálint Náfrádi

The transition metal tellurium oxychloride, Ni-5(TeO3)(4)Cl-2, has been investigated by high-field electron-spin resonance for frequencies up to 3 THz, at temperatures well below the magnetic ordering at 23 K. At zero external field several resonance modes ...

Hexagonal Versus Orthogonal Lattices: A New Comparison Using Approximation Theory

Dimitri Nestor Alice Van De Ville, Thierry Blu

We provide a new comparison between hexagonal and orthogonal lattices, based on approximation theory. For each of the lattices, we select the “natural” spline basis function as generator for a shift-invariant function space; i.e., the tensor-product B-spli ...

Channeling effects in heavy-ion irradiated NiAl(100) single-crystals: a TEM assessment in cross-section geometry using weak-beam imaging

A transmission electron microscopy (TEM) study using weak-beam imaging has been addressed in order to assess the microstructure of NiAl (100) single-crystals subsequently to irradiation at room temperature with 700 keV nickel ions up to 10(15) cm(-2) or 1. ...

Quasicrystalline nature of quasicrystal surfaces: A photoemission study

Differently prepared surfaces of quasicrystalline i-Al-Pd-Mn are analyzed using angle-resolved photoemission in the X-ray and ultraviolet range of photon energies. Depending on the preparation, we find both surfaces with crystalline structure and metallic ...

Interactive Web-based tools for an introductory course in crystallography

Gervais Chapuis

The new possibilities offered by the Java programming environment combined with the accessibility of the World Wide Web present new and interesting perspectives. It is thus now possible to perform simulations directly, using a Web browser, independently of ...

Strain and surface morphology in lattice-matched ZnSe/InxGa1-xAs heterostructures

Jean-Daniel Ganière

Lattice-matched ZnSe/InxGa1-xAs heterostructures were fabricated by molecular beam epitaxy on GaAs(001)2x4 surfaces. We find that the partial character of the strain relaxation within the ternary layer can be compensated by a suitable excess in the In conc ...

Characterization of semiconductor sub-micron gratings: Is there an alternative to scanning electron microscopy?

Jean-Daniel Ganière, Martin Achtenhagen

The characterization of sub-micron gratings is usually performed on scanning electron microscopes, although the dimensions of the features often make the observations difficult. We report here on a new method applicable to III-V and II-VI semiconductors: w ...
