Figure 1

(a,b) SEM images of the cross-section of the vertically aligned Ba-Ta3N5 nanorod arrays. (c) High-resolution transmission electron microscopy image of a Ba-Ta3N5 nanorod, taken along the [100] zone axis. (d) Corresponding selected area electron diffraction pattern acquired from the nanorod in c. (e) Crystal structure of Ba-Ta3N5 viewed from the [100] crystallographic direction (from 3D-EDT data). (f) ABF and (g) HAADF scanning transmission electron microscopy images of a Ba-Ta3N5 nanorod. Simulated cells of Ba-Ta3N5 are overlaid in f and g. Scale bars, (a) 300 nm, (b) 100 nm, (c) 10 nm, (f,g) 0.5 nm.
