摘要：
Ultra-thin metal overlayers on single crystal metal surfaces are novel, stable surfaces with physical properties which may be tailored for specific applications. The growth, structure and thermal stability of chromium and iron pseudomorphic monolayers and multilayers on W(110) are characterized by temperature programmed desorption, low energy electron diffraction, Auger electron spectroscopy and valence band photoemission. Surface-sensitive Cr, Fe and W core-level synchrotron photoemission is used to probe the local electronic changes at clean and oxygen-modified bi-metallic interfaces. Nitrogen chemisorption is used to illustrate the unique chemical properties of these overlayer systems. © 1990 IOP Publishing Ltd.
