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
