TEM and HRTEM images and EDS spectra of LSMO nanolayer and In ₂ O ₃ epitaxy. (a) Low-magnification TEM image of the LSMO nanolayer with In₂O₃ epitaxial buffering on the sapphire substrate. The HRTEM image was taken from the interface of the In₂O₃ epitxay-sapphire substrate (white square region), and the inset shows the corresponding electron diffraction pattern at the heterointerface. (b) HRTEM image taken from the local single LSMO nanograin on the In₂O₃ epitaxy. (c, d) HRTEM images taken from the different local regions containing two neighboring LSMO nanograins on the In₂O₃ epitaxy. The corresponding FFT patterns taken from the different oriented LSMO nanograins are also shown in the insets of (d). (e) EDS spectrum taken from the LSMO nanolayer. (f) EDS spectrum taken from the In₂O₃ epitaxy.
