Removal of core hole distortion from ionization edges in electron energy loss spectroscopy (2021)
Journal Article
Mendis, B., & Ramasse, Q. (2021). Removal of core hole distortion from ionization edges in electron energy loss spectroscopy. Physical Review B, 103(20), Article 205102. https://doi.org/10.1103/physrevb.103.205102

The near-edge fine structure in electron energy loss spectra is used to probe the electronic bonding environment of materials at high spatial resolution. Often, however, deviations from the ground state electronic properties are observed, due to the...
