Sequence of TEM images showing Au-Ge NW tip at different temperatures and the corresponding transformations. (A) During NW growth at constant digermane pressure (adapted from [26]); (B) under vacuum annealing (adapted from [27]). (C) Au-Ge binary alloy phase diagram outlining new liquidus lines for NWs with different diameters, respectively (adapted from [27]).
