摘要：

Atoms on the move: NO2 lifts the Au{111} herringbone surface reconstruction at 78 K through a massively cooperative restructuring step, which involves on the order of 600 NO2 molecules (blue; see STM image) and 80-100 Au atoms. Mesoscopic island ordering is a precursor to the process, and Au nanoclusters (green/yellow) form as the restructuring proceeds. (Figure Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
