摘要：
The surface structure of monolayer graphite (MG) on a Ni(111) surface has been investigated using Li+-impact collision ion scattering spectroscopy (ICISS) and reflection high-energy electron diffraction (RHEED). The RHEED pattern showed a 1 × 1 structure for MG formed on the Ni(111) surface, and the ICISS measurement clearly showed the difference between a clean Ni(111) surface and that with MG. The surface structure was determined via comparison of computer simulations and ICISS measurements. The C atoms locate on top and hollow sites of the Ni(111) surface, to form monolayer graphite, which is consistent with the model proposed by a tensor Low energy electron diffraction study.
