Abstract

Helium atoms are an established, non-invasive probe of surfaces. The interaction between the atom and the surface, in the thermal energy regime, is predominantly one of elastic scattering that gives surface sensitivity without perturbation to the electronic or physical properties of the surface itself. Recent work has been directed at beam focusing, with the aim of creating a microprobe. All the key atom-optical components necessary for the construction of a scanning helium microscope (SHeM) are now in place and such a microscope is currently under development. We present an overview of the technique, with particular reference to the potential contrast mechanisms.
