a,b STEM image of LNO and LNAW samples. c LNAW corresponding EDS mappings of Ni, O, Al and W elements. HAADF-STEM images and corresponding atomic structure of the phase boundaries observed in d LNO and e LNAW materials. FFTs from marked regions are also presented. f Line-profile analysis utilizing STEM-EDS.
