摘要：

The Pt/p-WSe2 interface has been studied by synchrotron induced core-level and He I excited valence band photoelectron spectroscopy. Platinum forms a continuous metallic overlayer. The deposition of platinum creates selenium defects at the surface leading to an initial band bending of 540 meV which is reduced by subsequent deposition of platinum. The origin of the reactivity is attributed to the high condensation energy of the deposited metal rather than to a possible metal exchange reaction.
