Multilayer Relaxation of a Clean Bcc FE(111) Surface

Abstract

A multilayer low energy electron diffraction analysis of the iron (111) surface structure has determined four interlaying spacings. This analysis is a refinement of an earlier analysis that used the same experimental data, but considered only variations of the first interlayer spacing. The first interlayer spacing shows a small increased contraction, but substantial changes are found in the deeper spacings. The optimized structure is (with dik the spacing between ith and kth atomic layer) delta d12=(-16.9 + or - 3.0)%, delta d23=(-9.8 + or - 3.0)%, delta d34=(4.2 + or - 3.6)%, and delta d45=(-2.2 + or - 3.6)%, relative to the bulk spacing of 0.827 A.
