Investigating the structure and dynamics of surfaces with high spatial and / or temporal resolution is a rich field of fundamental science with strong technological implications. A detailed understanding of the nanoscale structure and dynamics of surfaces lies at the heart of innovation in areas as diverse as materials growth and self-assembly; nanoscale control of the electronic and magnetic properties of materials (which increasingly includes control at the quantum level); and chemical processes such as catalysis and sensing. Cutting edge developments in instrumentation and analysis techniques have always underpinned our ability to probe ever smaller and faster; e.g., the invention of the scanning tunnelling microscope (STM) provided the capability to “see” individual atoms, while the invention of quasi-elastic helium atom scattering (QHAS) provided the ability to probe dynamics at surfaces with picosecond time resolution.
This symposium is composed of six invited talks from national and international leaders in the field of nanoscale structure and dynamics of surfaces utilising a range of techniques from He atom scattering, to scanning probe, to synchrotron radiation.
The symposium will serve as a platform for the award of the 2018 BVC Senior Prize and John Yarwood Memorial Medal to Dr William Allison of University of Cambridge for his contributions to understanding the structure and dynamics of surfaces using Helium Atom Scattering techniques. The British Vacuum Council (BVC) was founded in 1959 and is the national representative vacuum body for Britain and Ireland affiliated to the International Union for Vacuum Science, Technique and Applications (IUVSTA).
