Figure Lengend Snippet: a , Basic crystal structure of LLTO, consisting of alternating Li-rich and -poor layers and Ti and O octahedra. b , Calculated partial density of states (DOS) for LLTO and indicated transitions for the XUV-SHG probe. c , Overview of the experimental setup used for measurement of XUV-SHG data in reflection geometry. The inset shows the layered sample structure with repeating layers of LLTO and LCO. d , Schematic representation of an LCO–LLTO stack forming a prototypical battery, with the XUV-SHG process indicated on the top surface; note that LLTO is polycrystalline in the film measured despite the schematic representation. XFEL, X-ray free-electron laser. MCP, microchannel plate.
Article Snippet: The beam was dispersed using a diffraction grating with 1,200 grooves mm –1 before collection on a microchannel plate detector (Rectangular, Hamamatsu Photonics) coated with CsI.
