Neutral helium atom microscopy, also referred to as scanning helium microscopy and
commonly abbreviated SHeM or NAM (neutral atom microscopy), is a novel imaging …

The dissociative chemisorption of hydrogen at metal surfaces is the first step in the surface
chemistry of heterogeneous catalysis. Up to now, most of our understanding of this process …

The study of surface phonon dispersion curves is motivated by the quest for a detailed
understanding of the forces between the atoms at the surface and in the bulk. In the case of …

The chemical mechanical polishing (CMP) technology has been widely used for surface
modification of critical materials and components with high quality and efficiency. In a typical …

A method is described for levitating micron-sized few-layer graphene flakes in an electric
quadrupole ion trap. Starting from a liquid suspension containing graphene, charged flakes …

It is shown that the surface of an epitaxial graphene monolayer grown on Ru (0001) could
be used as a quite efficient external mirror for He-atom microscopy, with a specular …

Delicate structures (such as biological samples, organic films for polymer electronics and
adsorbate layers) suffer degradation under the energetic probes of traditional microscopies …

We report helium diffraction from graphene grown by chemical vapour deposition (CVD)
using copper foil. This method reveals acoustic phonons, which are physically important to …

Scanning surfaces using a beam of noncharged atoms or molecules allows for especially
nondestructive and low-energy surface imaging, with the potential to obtain new information …

The structure and the low-energy phonon dispersion of graphene (Gr) on Ni (111) have
been experimentally investigated with helium atom scattering (HAS). The Rayleigh mode …
