    Sammanfattning : The role of interfaces in oxide thin films has been investigated from a microstructural point of view. Thin films of manganites and titanates have been investigated by transmission electron microscopy (TEM). LÄS MER

  3. 2. Micromachined epitaxial colossal mognetoresistors for uncooled infrared bolometer

    Författare :Joo-Hyung Kim; Alexander M. Grishin; Yael Nemirosky; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; La0.67 Sr; Ca 0.33MnO3 LSCMO ; La0.67Sr0.33MnO3 LSMO ; Electrophysics; Elektrofysik;

    Sammanfattning : High quality perovskite manganites, La1-xAxMnO3 (A = Ca, Sr, Ba) are very attractive materials due to their great application potential for magnetic memory, uncooled infrared (IR) microbolometer and spintronics devices. This thesis presents studies of the growth and material characterization (including structural, electrical, magnetic and noise) of epitaxial manganite films on Si and GaAs. LÄS MER

  4. 3. A Comparative Study of the Performance of Concurrency Control Algorithms in a Centralised Database

    Författare :Donald F Ross; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : "The performance of Concurrency Control Algorithms (CCAs) in databases has been widely studied over the last ten years, mainly using analytic and simluation techniques. Results have been contradictory. The main CCA categories to emerge are locking, timestamping and serial validation. LÄS MER

  5. 4. Thin Films and Multilayers of Yba2Cu3O7-δ and Srtio3; Growth, Characterization, And secondary Phase Formation

    Författare :Niclas Edvardsson; Michael Karkut; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sputter-deposited thin films and multilayers of YBa2Cu3O7-δ (YBCO) and SrTi03 (STO) have been grown and studied. Microstructure in general, and formation of secondary phases, in particular, have been studied in relation to growth conditions. LÄS MER
