Fig. 4
The formation of a liquid shell in Au nanoclusters at high temperatures. a HAADF STEM images of an Au561 particle at high temperatures (650–857 °C). b HAADF STEM images of an Au1110 particle at high temperatures (704–1000 °C). Amorphous regions at the edges of the particle are highlighted by yellow arrows. c A line profile plot of the HAADF intensity across the particle in (a) at 857 °C and d a line profile plot of the HAADF intensity across the particle in (b) at 1000 °C. Black arrows on the HAADF intensity plots illustrate amorphous regions. Yellow arrows on the inset HAADF images indicate the direction and location of the line profile
