1. 1. Control of Defects and Subgrains in Epitaxial Perovskite Thin Films

   Författare :Lars Ryen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thin film evolution; La0.70Ba0.30MnO3; epitaxial perovskite films; Keywords: TEM; dielectrics; EELS; SrTiO3; YBa2Cu3O7-x; superconductors; colossal magnetoresistance;

   Sammanfattning : This work concerns the microstructure of epitaxial (001) perovskite thin films, studied by transmission electron microscopy (TEM), in particular high resolution TEM, electron energy-loss spectroscopy (EELS), and energy dispersive x-ray analysis. The perovskites exhibit interesting superconducting, dielectric, and magnetic properties. LÄS MER
