摘要：
Ultrathin metal overlayers on W(111) are studied by high-resolution photoelectron spectroscopy using synchrotron radiation. The bimetallic systems are prepared by adsorbing approximately one monolayer of K, Cc, Ni, Pd, Pt: Cu, Ag and Au on W(111) at 100 K. The W 4f(7/2) core levels from the W(111) substrate are measured. It is found that the core-level W 4f(7/2) binding energy shifts originating from W atoms at the interface correlate well with the heats of adsorption for metal films on W(111).
