Title: Domain mixtures in the NiAl(111) surface

Abstract

The NiAl(111) surface structure has been determined using low-energy electron diffraction (LEED) I--V intensity analysis. From considerations of the stacking sequence of the (111) planes in the bulk, the surface would be expected to be terminated in one of two types of domains, i.e., in a layer of Al atoms or of Ni atoms. The results of the LEED analysis demonstrate that the NiAl(111) has ordered domains of both Al- and Ni-terminated layers. Importantly, the relaxations within the two types of domains are determined to be significantly different as well.
