Study of fullerenes on Au (111) surfaces using STM

[摘要] A variable temperature scanning tunnelling microscope (VTSTM) was used to study (C\(_{60}\))\(_m\)-(Au)\(_n\) magic number clusters as well as the sputtering Au (111) surface. Formation of C\(_{60}\) - Au magic clusters was previously reported. Here a more in depth study of the clusters as well as conditions required to control the sizes and positions are presented. This is then followed by studies of topographical changes after sputtering Au (111) surface, with and without C\(_{60}\) islands. Results obtained from this investigation indicated the stronger binding of broken fullerence cages with each other or the gold surface.
