Abstract
In this short communication we describe some software techniques for electron energy‐loss spectrum measurement. We prepared DigitalMicrograph (Gatan) scripts for multiple spectrum acquisitions, quasi‐simultaneous acquisition of low‐loss and core‐loss spectra, energy drift correction, and other operations. Narrow zero‐loss spread of 0.27 eV is demonstrated using a 300 kV field‐emission transmission electron microscope (TEM) (Hitachi, HF‐3000) and a post‐column energy filter (Gatan, GIF2002). The core‐loss spectrum is acquired with an energy resolution of 0.36 eV with high reproducibility. The present software techniques effectively achieve the intrinsic energy resolution of electron sources. Sample scripts are provided in the Appendix.Keywords
