| Résumé | Energy electron-loss spectroscopy (EELS) often requires extensive post-processing for quantitative interpretation of measured spectra [1, 2]. Often the first step in spectra interpretation involves removal of plural scattering, which can be accomplished by Fourier-log deconvolution. The spectral features are often broadened by various instrumental factors including detector response, electron-source energy width and various instabilities. Here we show that Fourier-log deconvolution followed by Richardson-Lucy deconvolution both removes plural scattering and sharpens the spectral features of the recorded spectra without introducing obvious artifacts [3]. We demonstrate the performance of two-step deconvolution using a hexagonal Boron Nitride (hBN) sample suspended over holes in a lacey carbon film. The boron-K edge, shown in Figure 1, exhibits rich near-edge fine structure, as discussed in detail in [4]. As a measure of the energy resolution of the spectra at the core-edge energy loss, we use the width of the peak A at 192 eV and the separation of the splitting in peak B at 198 eV in Figure 1. |
