Forschungsgebiete

Prozess-Struktur-Eigenschaftsbeziehungen an Systemen mit reduzierten Dimensionen bzw. defektreichen Systemen (z.B. an Material-Wasserstoff M-H Systemen). M-H Systeme bieten neben der Möglichkeit des Grundlagenstudiums physikalischer und materialwissenschaftlicher Effekte das Anwendungspotential als Energiespeicher der Zukunft.

  • Thermodynamik und Kinetik von nanoskaligen Werkstoffen (Nanopartikel, perkolierende Schichten, Schichten und Multilagen bis hin zu defektreichen Metallen)
  • mechanische Spannungen und "Finite-Size"-Effekte
  • Versprödung von Konstruktionsmaterialien
  • spezielle Eigenschaften nanokristalliner Werkstoffe, amorpher Metalle und Werkstoffen unter inneren mechanischen Spannungen
