摘要：
The work function of Na-deposited TiO2(110) surfaces was mapped using a Kelvin probe force microscope (KPFM). Individual Na adatoms were identified as topographic protrusions on atomically flat terraces of the TiO2 surface. The work function locally decreased by 0.1-0.5 eV on each adatom. The observed modulations of work function were interpreted with the electric permanent dipole moment caused by the electron transfer from the adatom to the substrate.
