Attenuation lengths of low-energy electrons in solids

Structural studies of alkali metal adsorption and coadsorption on metal surfaces

The authors show how the elementary concepts which govern the bulk total energy and crystal structure of sp bonded metals are also relevant at the surface. A simple model explains the observed contraction in the interlayer spacing of the (110) surface layer of aluminium compared with the (100) and (111) surfaces.

Theory of lattice contraction at aluminium surfaces

Electron structure of Na and K adsorbed on Ni (100)

A tabulation and classification of the structures of clean solid surfaces and of adsorbed atomic and molecular monolayers as determined from low energy electron diffraction patterns

The authors are concerned with extraction of structural information from LEED intensity measurements by comparison with dynamical calculations for trial structures. The technique is illustrated by the system of sodium on a nickel (100) surface. Experiments are described; resolution is investigated and found to be about +or-0.1 AA. The top layer of a clean nickel (100) surface is shown to be dilated by not more than 0.15 AA and the determination of the sodium nickel distance of 2.9 AA reported earlier by Andersson and Pendry is described in greater detail.
