Title: Atomic structure of three low-index surfaces of the ordered binary alloy NiAl

Abstract

The atomic structures of the (110), (100), and (111) surfaces of NiAl have been determined by LEED I-V analysis. Results obtained for these surfaces serve as illustrations of three general crystallographic effects that can exist in the surfaces of ordered alloys. The three effects are the rippling of atomic constituents in the outermost composite layer of NiAl(110), preferential termination by one of two possible layers at the NiAl(100) surface, and the mixture of domains of the two possible terminations at the NiAl(111) surface.
