Abstract
Pt/C multilayers of nanometric dimension have been irradiated with 2-MeV-Au ions to a fluence of 1× 1014ions/cm2 and analyzed by x-ray reflectivity and x-ray standing wave measurements. The multilayer period has expanded by ~9%, the expansion of the Pt layers being larger than that of the C layers. Ion-induced displacement of atoms across the interfaces led to an increased interface roughness and an increase of 2 at % Pt in C layers. Monte Carlo simulations for ion-induced atomic displacement have been used to explain the observed effects.
