Abstract

We report controlled manipulation of magic number gold–fullerene clusters, (C60)m–(Au)n, on a Au(111) substrate at 110 K using scanning tunneling microscopy (STM). Each cluster consists of a two-dimensional gold island of nAu atoms confined by a frame of mC60 molecules. Using STM, C60 molecules are...
