  4. 3. Metastable YAlN and ScAlN thin films : growth and characterization

    Författare :Agnė Žukauskaitė; Lars Hultman; Jens Birch; Anita Lloyd Spetz; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : ScxAl1-xN and YxAl1-xN thin films were deposited in a ultra high vacuum system using reactive magnetron co-sputtering from elemental Al, Sc and Y targets in Ar/N2. Their mechanical, electrical, optical, and piezoelectrical properties were investigated with the help of transmission electron microscopy, xray diffraction, ellipsometry, I-V and C-V measurements, and two different techniques for piezoelectric characterization: piezoresponse force microscopy and double beam interferometry.

  5. 4. Silicon nanowires, nanopillars and quantum dots : Fabrication and characterization

    Författare :Robert Juhasz; Jan Linnros; Philippe M. Fauchet; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon nanowires; silicon nanopillars; silicon quantum dots; size-reduction; thermal oxidation; electrochemical etching of silicon; photoluminescence; Semiconductor physics; Halvledarfysik;

    Sammanfattning : Semiconductor nanotechnology is today a very well studied subject, and demonstrations of possible applications and concepts are abundant. However, well-controlled mass-fabrication on the nanoscale is still a great challenge, and the lack of nanofabrication methods that provide the combination of required fabrication precision and high throughput, limits the large-scale use of nanodevices.
