Local EELS spectra acquired from Au-X on top of graphene.

(a) Original energy loss and extracted carbon K edge at 284 eV (b) Original energy loss and extracted gold M5 edge at 2206 eV. (c) EELS spectrum obtained within energy range from 80 to 280 eV showing no signal of the Si-K edge at 99 eV. (d) EELS spectrum obtained within energy range from 370 to 570 eV, the signal at around 540 eV could originate from gold (N2,3 edge) or oxygen (K edge).
