The Surface Nanoscience Research Group is in the Department of Materials at the University of Oxford. We study the atomic scale structure and properties of surfaces and nanostructures, and also investigate molecular ordering on surfaces. Our main instruments are two JEOL ultra high vacuum (UHV) scanning tunnelling microscopes (STM) that can image surfaces at atomic resolution over a wide range of temperatures. We have recently installed a third UHV chamber to process materials for a gas sensing project. We also have a custom-built chamber to test our gas sensors for a variety of low concentrations of analytes. By characterising and processing surfaces on the nanoscale we aim to create new materials for applications in catalysis, gas sensing, microelectronics, and diverse areas of nanotechnology.
