THE PHYSICAL AND ELECTRONIC STRUCTURE OF THE Cu85Pd15(110) SURFACE: CLUES FROM THE STUDY OF BULK CuxPd1−x ALLOYS

The (110) surface of Cu 85 Pd 15 adopts an ordered structure which can be controlled by Ar bombardment and thermal treatment. A summary is given of the large body of theoretical and experimental work on the physical and electronic structure of bulk Cu x Pd 1−x alloys. The electronic structure of the ordered Cu 85 Pd 15(110) surface is discussed in terms of the conclusions drawn from the study of bulk CuPd alloys.
