Ultramicroscopy Research Group

The Ultramicroscopy group is based around exploring the design and function of the aberration-corrected scanning transmission electron microscope (STEM). Based in the Advanced Microscopy Laboratory, we work to improve the acquisition and analysis of atomic-resolution annular dark-field (ADF) data and EELS and EDX chemical mapping. Themes include ADF normalisation by detector efficiency, correction of scan-noise and scan-distortion and correction of artefacts in EELS spectra. As part of this research, a series of image analysis and processing codes have been written to inspect, improve and quantify atomic-resolution ADF STEM data.
