  2. 2. Metastable orthorhombic Ta3N5 thin films grown by magnetron sputter epitaxy

    Author : Jui-Che Chang; Ching-Lien Hsiao; Jens Birch; Grzegorz Greczynski; Denis Music; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The semiconductor tritantalum pentanitride (Ta3N5) is a promising green-energy material for photoelectrolyzing water to produce oxygen and hydrogen owing to its proper bandgap of 2.0 ± 0.2 eV and band positions to redox potential of water. READ MORE

  3. 3. Functional Interfaces in Epitaxial YBa2Cu3O7-δ with Artificial Grain Boundary Junctions

    Author : Henrik Pettersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The properties of superconducting devices based on grain boundaries in YBa2Cu3O7-δ (YBCO) thin films are determined by the atomic structure of the grain boundary plane. To obtain these devices based on single grain boundaries, biepitaxial fabrication techniques has been used. READ MORE
