Lewys Jones

Dr Lewys Jones is an Ussher Assistant Professor of Ultramicroscopy in the School of Physics, Trinity College Dublin. He leads the Ultramicroscopy research group, focussed on instrument and technique development for high-performance electron microscopy.

Dr Jones current research in metrology development is based around exploring the design and function of the aberration-corrected scanning transmission electron microscope (STEM), to improve the 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.
