Examensarbeiten in der Abteilung Strukturmaterialien

  • Modification of nanostructures by particle irradiation and/or thermal processing
    (Computational Materials Science)
    Subjects:
    - ion irradiation and subsequent thermal treatment of Si and Ge, in particular in nanowires, in order to obtain electrical doping: implantation of dopant atoms, formation and evolution of defects, solid phase recrystallization, role of dopants, impurities and interfaces, influence on electrical properties
    - nanostructure evolution in iron-based structural materials of nuclear reactors during materials fabrication and neutron irradiation: formation and evolution of defects, nanoclusters, dislocations and their mutual interaction, role of grain boundaries, influence on mechanical properties
    Methods:
    - first principle calculations, classical-interatomic-potential methods
    - molecular dynamics and statics, Monte Carlo simulations
    - high-performance computing
