Figure 6: Analysis of EELS data.
From: Unravelling structural ambiguities in lithium- and manganese-rich transition metal oxides
(a) series of EEL spectra showing the surface (top) and the bulk (bottom) corresponding to the HAADF image in Fig. 5a, (b) Mn L3 and L3 edges for the bulk and the surface, showing the presence of eg−t2g split corresponding to the bulk region and the chemical shift to lower energy corresponding to the surface. (c,d,e) L3/L2 ratio corresponding to Mn, Co and Ni, respectively, showing decrease in oxidation states for Mn and Co at the surface.
