Figure 10
(a) ADF and (b) ABF atomic resolution STEM images of the nolanite-type phase along the [100] direction. The inset images are generated by unit-cell averaging, and the crystal structure model of Cr2_HH266 is overlaid. The metals are shown as larger balls (Sn gray, Ge light blue) and the anions as smaller balls (O red, N blue). The numbers in the left inset indicate a stacking of one or two germanium atoms per unit cell in the direction of observation.
