Fig. 3: The versatility of lattice-mismatch-free construction of III–V/chalcogenide core–shell heterostructure NWs.
From: Lattice-mismatch-free construction of III-V/chalcogenide core-shell heterostructure nanowires
a–c The SEM image, HRTEM image and EDS elemental mapping images of GaAs/GeS core–shell heterostructure NWs. d–f The SEM image, HRTEM image and EDS elemental mapping images of InGaAs/GeS core–shell heterostructure NWs. g–i The SEM image, HRTEM image and EDS elemental mapping images of GaSb/GeSe core–shell heterostructure NWs. The insets in (b, e, f) show the corresponding FFT images of the core and shell regions, respectively. All the scale bars in (c, f, i) are 20 nm.
