摘要：

The phonon dispersion relations of monolayer graphite on Pt(111), NbC(111) and NbC(001) were measured by electron energy loss spectroscopy. The monolayer graphite on Ni surfaces has been reported to show large softening, while that on Pt(111) was found to indicate little softening and rather resembled pristine graphite. Similarly, the monolayer graphite on NbC(111) indicated fairly large softening but that on NbC(001) did not. This difference is discussed in relation with the interface structure.
