Extended Data Fig. 8: Quantitative chemical mapping analysis of YBa2Cu3O6.5 using super-EDS.
From: Topological spin texture in the pseudogap phase of a high-Tc superconductor
a, HAADF-STEM image indicating the area in which the EDS map is acquired from the red dotted box in g. b–e, Chemical component maps of Y, Ba, Cu and O, respectively. f, Chemical component spectrum over the whole mapping area. g, Electron micrograph of YBa2Cu3O6.5 obtained in the in-focus Fresnel mode of LTEM. The inset shows the corresponding electron diffraction. h, Table showing quantitative analysis of the chemical composition, which is consistent with YBa2Cu3O6.5.
