  1. 1. Kinetic Monte-Carlo studies of island shape evolution on weakly-interacting substrates

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Filip Thunström; [2018]
    Nyckelord :Kinetic Monte Carlo; thin film; metal; weakly interacting substrates;

    Sammanfattning : Metal thin films deposited on weakly-interacting substrates constitute an essential element of numerous microelectronic, catalytic, and optical devices. However, the natural tendency of metal atoms to agglomerate, upon condensation on a weakly-interacting surface, in dispersed three-dimensional (3D) islands affects negatively the performance of the above-mentioned devices.

  3. 2. SiC Homoepitaxial Growth at High Rate by Chloride-based CVD

    Master-uppsats, Linköpings universitet; Institutionen för fysik, kemi och biologi; Halvledarmaterial

    Författare :Yuan-Chih Lin; [2010]
    Nyckelord :silicon carbide; chloride-based CVD; homoepitaxial growth; tungsten incorporation;

    Sammanfattning : SiC is an attractive material since it has remarkable properties. For several years efforts have been put primarily in electronic applications. High power and high frequency devices can be fabricated on SiC due to its wide band gap, high breakdown field and high thermal conductivity. LÄS MER

  4. 3. Investigation of Structural and Optical Properties of Nanocrystalline ZnO

    Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

    Författare :Sajjad Hussain; [2008]
    Nyckelord :Investigation; Structural; Optical; Properties; Nanocrystalline; ZnO;

    Sammanfattning : The structural quality of material (concentration and nature of defects) and optical properties (intensity and spectral emission range) of semiconductor materials are usually closely correlated. The idea of this work was to carry out a basic characterization of the structural (by X-ray diffraction technique and scanning electron microscopy) and optical (by micro photoluminescence measurements) properties of nanocrystalline ZnO samples and find a correlation.
