摘要：

High-resolution core-level-photoemission investigations of the (100), (111)-1 X 1, and (111)-8 X 1 surfaces of VC0.8, using synchrotron radiation are reported. Surface-shifted C Is levels were observed on all three surfaces while surface-shifted V 2p levels could not be identified on any of the surfaces. The surface core-level shifts were extracted using a curve-fitting procedure. For the major surface-shifted component which was identified on all three surfaces, a shift of - 0.33(+/-0.02) eV was determined. For the (111)-8 X 1 surface a second shifted component having a shift of + 0.44(+/-0.02) eV was identified.
