Fig. 1: Single-atom-layer traps (SALTs) in LLTO.
From: Single-atom-layer traps in a solid electrolyte for lithium batteries
a–d HAADF-STEM images of the 2D defects that formed SALTs. The LLTO planes parallel with the 2D defects are marked directly in images. A La-rich A-site layer and a La-poor one in LLTO were indicated by solid and empty arrows, respectively, in b. The red circles indicated three A-site atomic columns that were located in the La-poor layer of LLTO but became La-rich because of the neighboring 2D defect layer. e Ubiquitous presence of SALTs. The bright arrows indicated three 2D defects that appeared less dark due to the coexisting LLTO in their atomic planes. The scale bars in a, b, c, d and e are 5 nm, 2 nm, 5 nm, 5 nm and 10 nm, respectively.
