Die Struktur von Quasikristallen erlaubt phasonische Flips, das heißt Atome können auf alternative Positionen springen, ohne daß die Gesamtstruktur verändert wird. Schwerpunkt der Arbeit ist das Auffinden dieser phasonischen Flips in AlCuCo mit Hilfe molekulardynamischer Simulationen. Zum Aufspüren dieser Flips wurde in ein vorhandenes Molekulardynamikprogramm ein Flip-Detektor implementiert. Zur genaueren Untersuchung der gesamten Atombewegungen wurde eine Methode zur interaktiven Darstellung des gesamten zeitlichen Verlaufs einer Simulation entwickelt. Neben den erwarteten korrelierten Sprüngen in den dekagonalen Schichten sind weitere korrelierte Bewegungen im Quasikristall sichtbar.The structure of quasicrystals permits phason flips: at...
