Valence Electron Energy Loss Spectroscopy

Figure Caption. Spatially resolved valence electron energy loss spectroscopy (Sr-Veels) in the scanning transmission electron microscope is a localized (~1
nm probe) electronic structure tool for interfacial electronic structure studies. Here the Sr-Veels spectra versus energy (0 to 80 eV) and distance (0 to 10
nm) across and intergranular film in silicon nitride is shown. The data is multiplexed for zero loss optimized / plasmon optimized spectral acquisition to
maximize the signal to noise ratio.
