  4. 3. High resolution microstructural characterization of oxide thin films and interfaces

    Författare :Nikolina Tuzla; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxides; Microstructure; TEM; thin films; interfaces; HAADF STEM; YSZ.; SrTiO3; 2DEG; LaAlO3; heterostructures;

    Sammanfattning : Oxide interfaces can introduce properties that are different compared to thecorresponding crystal bulk properties. The properties can be tuned by changing thestructure. It has become clear that these oxide interface systems are potentiallysuitable for future electronic devices with unique and tailored properties. LÄS MER
