X-ray photoelectron and emission spectroscopies (XPS and XES) are fundamental tools for characterizing the chemical composition of materials at their surfaces. Conventional instrumentation can only probe samples under vacuum conditions, and hence volatile or aqueous samples must be frozen prior to measurement. This can change the sample behaviour and makes it difficult to monitor evolution over time.
Through funding from the Royce Institute, we are developing a bespoke instrument that will establish the world’s first multi-technique X-ray core level spectroscopy facility for the characterization of materials under natural environmental conditions. This will enable measurement of samples and devices containing volatile components (e.g. solvents, adsorbed gases, biological and biomaterials, pastes and suspensions) without cryogenic cooling for the first time.
It will also allow investigation of electrically insulating samples, studies of whole devices and dynamic processes, and depth profiling of molecular materials, all under environmental conditions. The facility will link directly with the Leeds beam-line at the Diamond Light Source - the UK’s national synchrotron facility.
