Abstract
We have conducted a study of the growth of C60 and C70 on a variety of reconstructed and unreconstructed noble metal surfaces using a UHV sc anning tunneling microscope. For reconstructed Au(110) and Au(111) sur faces we observe changes in the superstructure of the metal upon (sub) monolayer adsorption at the fullerene-metal interface. In all the meta ls studied, formation of a well-ordered hexagonal C60 overlayer is obs erved after annealing. (110) and (111) substrates show preferred nucle ation and growth at terrace and steps, respectively. Time-lapsed image s illustrate mobility of C60 arrays and clusters. The role of tip-C60 interactions is elucidated by sequences of images and the prospects fo r manipulation is discussed.
