TEM and HRTEM images and EDS spectra of LSMO nanolayer and In
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.
