TEM images and SAED patterns. The left image shows TEM images of multisegmented Co-Ni nanowires. The right image shows SAED patterns of the different nanowire segments marked in the left image of the figure. SAED pattern with number (1) can be indexed to the  zone axis of a Co-Ni alloy with a hcp structure. SAED pattern number (2) can be indexed to the [−321] zone axis of a Co-Ni alloy with a fcc structure.
