Fig. 4

Structural and composition analysis of InP and GaP nanowires. a, b HRTEM image of an InP nanowire, showing the ZB twinning superlattice structure. d, e TEM images of a GaP nanowire. f Fast Fourier transform image of the Au droplet, demonstrating the formation of AuIn2 phase. High-angle annular dark-field (HAADF) image of the same InP (c) and GaP (g) nanowires. h EDX spectra of points 1–4 in (c, g). EDX intensity is normalized and shifted for visibility
