摘要
Monolayer and multilayer La@C-82 films were epitaxially grown on MoS2 substrates, and their growth features together with electronic states were investigated using atomic force microscopy and electron energy loss spectroscopy. It was found that the interaction between a La@C-82 molecule and a MoS2 surface is stronger than that between La@C-82 Molecules. The electronic state of the initial La@C-82 layer on the MoS2 surface differs from that of the successively grown bulk-like layers due to excess electrons in the carbon cage of La@C-82.
