  1. Strain inhomogeneities in epitaxial BaFe2As2 thin films

    Epitaxial BaFe2As2 thin films grown on spinel substrates with a thin iron buffer layer show strain-induced superconductivity. Using high resolution electron backscatter diffraction in a scanning electron microscope very small orientation changes (≤ 0.2°) of the lattice and strain inhomogeneities on a length scale of few 100 nm or less were measured. Furthermore, partially strain relaxed areas were revealed. It was found, that the quality of the BaFe2As2 thin films crucially depends on the iron buffer layer.

  3. Investigation of structural, electronic and optical properties of pure and Ag-doped TiO2 nanofibers fabricated by electrospinning

    Nalan Çiçek Bezir, Atilla Evcin, Refik Kayalı, Murivet Kaşıkcı Özen and Ayşe Oktay

    Article first published online: 19 AUG 2015 | DOI: 10.1002/crat.201500159

    SEM images of the thermally untreated and treated and AFM image of thermally untreated with 3% Ag doped TiO2 nanofibers are seen. The diameters of thermally treated fibers decrease without having any change in their shapes much. AFM images at below shows that the nanofibers are developed as three-dimensional coils under the action two repulsive electric forces between the uniformly distributed charges carried with the jet.

  4. Growth of LaBGeO5 crystal fibers by the micro-pulling down technique

    Article first published online: 19 AUG 2015 | DOI: 10.1002/crat.201500161

    As the direct growth of LBGO fibers from the melt using micro-pulling down technique was unsuccessful because of its high viscosity, a flux is needed. The study of the LBGO-LiF phase diagram showed that LiF could be convenient. Several crystal fibers were then grown and characterized by Raman spectroscopy. Addition of B2O3 to decrease flux evaporation allowed to obtain a white cloudy fiber checked by Raman spectroscopy and SEM.

  5. Comment on “Debye temperature and melting point of II-VI and III-V semiconductors” [Cryst. Res. Technol. 45, No. 9, 920–924 (2010)]

    In this work we have improved and corrected some imperfections which have been found in Kumar et al. work. By correction of the expression of the mean atomic volume of binary zincblende semiconductors , some empirical parameters have been readjusted. However, the values of the Debye temperature calculated by Kumar et al. are not affected by these errors.
