Instrumentation




As part of its recently renewed contract with EPSRC, the SuperSTEM Laboratory is in the process of planning a significant infrastructure investment to develop its on-site sample preparation and materials nanofabrication expertise, with the aim to provide ultra-thin, damage-free specimens optimised for atomic-resolution STEM imaging and analysis.
