“…Despite having lower electronegativities for Al, Si, and P at 1.61, 1.86, and 2.2, respectively, compared to Au at 2.54, these elements tend to gain electrons, which results in a reduction of electron density in Au. [ 42–44 ] Consequently, the observed peaks in the 4f 7/2 binding energy approximately at 82.38, 83.18, and 83.98 eV are ascribed to negatively charged Au (Au δ− ), metallic Au (Au 0 ), and positively charged Au (Au δ+ ) species, respectively. However, the peak at 83.98 eV in the Au 4f spectrum is attributed to the combined influence of interactions, [ 42–44 ] Au‐P, Au‐Al, and Au‐Si, as per the STEM, EDS, and WDS findings.…”
