摘要：

The surface phonon dispersion relationship and electronic structure of a graphite monolayer on (111) and (001) surfaces of ZrC were studied by high-resolution electron energy loss and angle-resolved ultraviolet photoelectron spectroscopy. The graphite monolayer on the (111) surface shows larger softening in phonon structures and decreased pi-band initial state energy than on the (001) surface. These phenomena were discussed in the viewpoint of charge transfer from the substrate to the graphite overlayer and it was revealed that there was much more charge transfer for the C/ZrC(111) system than for the C/ZrC(001) system.
