  1. 6. From understanding to realizing novel III-Sb materials via nanowires

    Författare :Luna Namazi; NanoLund: Centre for Nanoscience; []
    Nyckelord :Fysicumarkivet A:2018:Namazi;

    Sammanfattning : Due to their unique physical and material properties, III-Sb nanowires are considered good candidates for future devices, and test beds for understanding fundamental physics. Synthesizing these nanowires however is associated with certain challenging aspects, which are generally not present for other III-V nanowires, demanding the need for in depth investigations.

  3. 7. Growth and Characterization of AlN : From Nano Structures to Bulk Material

    Författare :Gholamreza Yazdi; Rositza Yakimova; Mikael Syväjärvi; Zlatko Sitar; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Aluminum nitride (AlN) exhibits a large direct band gap, 6.2 eV, and is thus suitable forsolid state white-light-emitting devices. It is capable in spintronics because of its high Curietemperature if doped with transition metals. LÄS MER

  4. 8. Defects in Titanium Aluminum Nitride-Based Thin Films

    Författare :Janella Salamania; Magnus Odén; Lars Johnson; Lina Rogström; Zoe Barber; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thin films; Ti-Al-N; Defects; Physical vapor deposition;

    Sammanfattning : Coatings and thin films inherently contain several types of defects. This thesis aims to enhance the understanding of the relationship of defects on the growth, structure, stability, and properties of titanium aluminum nitride films synthesized by physical vapor deposition techniques.

  5. 9. Thermally and Optically Excited Electron Transport in Semiconductor Nanowires

    Författare :I-Ju Chen; Fasta tillståndets fysik; []
    Nyckelord :Fysicumarkivet A:2018:Chen;

    Sammanfattning : This thesis explores the transport of thermally and optically excited electrons invarious nanowire structures. On one hand, electrons are thermally excited when thetemperature is nonzero, and the thermal energy help them surmount energy barriersthat are present in the material. LÄS MER

  7. 10. ZrN based Nanostructured Hard Coatings : Structure-Property Relationship

    Författare :Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Andersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Ever since the hard coatings have been introduced, there has been a constant push for better mechanical properties, which motivates for deeper understanding of the microstructure-mechanical properties correlation. The aim of this thesis is to extend the knowledge on how microstructural variation influences the deformation, fracture and wear behavior of ZrN based nanostructured coatings. LÄS MER
