Imaging surfaces with atoms

If you have a question about this talk, please contact Stephen Walley .

Scanning helium microscopy is a novel form of microscopy which uses neutral low energy (less than 100meV) helium atoms to image the surface of a material or structure. The low beam energy leads to a technique which is exclusively surface sensitive and opens the possibility of studying materials that would be damaged by microscopies that use a higher beam energy. In this talk I will discuss the progress being made in developing an atom microscope, including the in-house production of a high sensitivity mass spectrometer and observed contrast mechanisms.

This talk is part of the Physics and Chemistry of Solids Group series.
