X-ray nanodiffraction in forward scattering and Bragg geometry of a single isolated Ag–Au nanowire

We study a single isolated Ag–Au nanowire with a nanofocused X-ray beam combining coherent diffraction methods in both forward scattering and diffraction geometries. X-ray scattering tomography measurements in forward geometry reveal a core–shell structure and allow determining the external size and...

Description
Summary:We study a single isolated Ag–Au nanowire with a nanofocused X-ray beam combining coherent diffraction methods in both forward scattering and diffraction geometries. X-ray scattering tomography measurements in forward geometry reveal a core–shell structure and allow determining the external size and shape of the nanowire. Bragg geometry measurements reveal the internal structure of the nanowire, notably the presence of stacking-faults in the nanowire. •A single bi-metallic Ag–Au nanowire was isolated for X-ray studies.•Tomography and Bragg coherent diffraction were performed on a single nanowire.•CDI reveals the internal structure of the single nanowire (strain, defects, …).
