Fig. 1: Lattice-mismatch-free construction of core–shell heterostructure NWs, taking GaSb/GeS as an example.
From: Lattice-mismatch-free construction of III-V/chalcogenide core-shell heterostructure nanowires
a–c TEM, cross-sectional HAADF STEM, and partial enlargement HAADF STEM images of the as-constructed core–shell heterostructure NWs. The inset of (c) shows the corresponding FFT pattern. d–g EDS elemental mapping images of Ga, Sb, Ge, and S, respectively. All the scale bars are 10 nm. h–j Diameter statistic, shell thickness statistic, and XRD patterns of as-constructed core–shell heterostructure NWs with different growth duration.
