Structural and chemical identifications of an AIST crystallite, stacked by bilayers and quintuple layers. a HAADF-STEM image; the arrows mark the quintuple layers between two bilayers. b–h EDX mappings for Ag, In, Sb, Te, Sb + Te, Ag + Te, and In + Te elements, respectively. I: corresponding schematic atomic stacking model of crystalline AIST. The scale bar is 0.5 nm
