Expansion, Motivation and Teaching,ssible. A procedure for the systematic analysis of the most likely spatial symmetries in three dimensional lattices is proposed, producing a number of possible crystal structures and, in favourable cases, after optimization of the packing potential energy, a completely ab initio crystal structure pr

In effect, this allows an analysis of the 9-dimensional potential hypersurface to be performed by searching a 3-dimensional, close-packed subspace. Use is made of geometric concepts, construction techniq

Lattice images are very noisy, but lattice information can be observed by He-Ne interferometry of the micrograph film (even in absenc

The aim of the paper is to illustrate some of the interpretational aspects involved in relating STM images to true structural detail
