Next generation microscopy with atoms and application to ice surfaces

We have recently developed a revolutionary new form of microscopy using neutral atoms. The method is ultra-sensitive, and will enable many previously inaccessible surfaces to be studied, ranging from light sensitive molecules, to polymers making up MEMS structures. The aim of this project will be to push the bounds of the technique, and explore the use of matter wave-effects in contrast formation (i.e. diffraction and interference contrast).

There will be particular emphasis on application of the technique to ice. Ice is a vitally important material, yet is still not well understood. A range of unusual and complex morphologies are formed during low-pressure growth, ranging from regular arrangements to complex ‘worm-like’ structures. However, it is almost impossible to study these structures at high resolution – electron microscopy causes melting, and scanning probe techniques cannot cope with the high aspect ratio structures that are formed. Helium microscopy represents a unique opportunity to understand these challenging structures for the first time.

The project is primarily experimental, but could be extended to include simulation/modelling depending on individual interests. It will involve working closely with the local team supporting the ongoing microscope development, as well as a series of international collaborators.
