Abstract
The nature of distinct bright-dim C60 contrast and its intricate ordering on Ag(100) is clarified with scanning tunneling microscopy. The C60 film is (111) close-packed with locally distorted rhombic units of specific contrast order, forming an incommensurate aperiodic phase. We relate the C60 contrast to an interfacial restructuring beneath each dim C60, with its ordering determined by competing interactions in the reconstructed interface and of the rhombus configuration. © 2003 The American Physical Society.
