Abstract
We report an unique planar defect that draws the Nazca Lines in epitaxially grown La 2/3-xLi 3xTiO 3 (LLTO) (x ≈ 0.11) ion-conductive perovskite. Transmission electron microscopy and electron energy loss spectroscopy reveal that the lines are produced by changing the regular arrangement of alternate stacks of La-rich and La-poor layers along the c-axis into all La-rich layers near the defect. The first-principle calculation suggests that the La-rich layers should act as a barrier to Li conductivity and are, therefore, important for the application of epitaxially grown LLTO thin films.
