A link between peaks in secondary electron (SE) spectra and Electron Energy Loss Spectra
(EELS) was shown decades ago. Also, materials properties (bulk modulus, band gap)
correlate with the bulk plasmon position in EELS, and local modulus maps in carbon fibres
have been presented. If any features as result of plasmon decay into SE can be identified,
SE spectroscopy combined with hyperspectral imaging could transform the SEM into a tool
for mapping materials properties with ground-breaking potential for nanotechnology. To
become a reality, we first need to establish SE collection conditions spectra that represent a
material reliably. Second, we need to gain a better understanding of the processes involved in the SE emission processes.
