Show affiliationsDetails of the vapour–liquid–solid Au droplet catalysed growth of ZnS nanobelts are elucidated in this work. The inclination of the Au droplet after solidification shows that it is indeed in the liquid state during nanobelt growth. Numerous stacking faults are observed when (0001) wurtzite is the side surface of the nanobelt. Compressive stress at the droplet–nanobelt–atmosphere triple interface is the cause of the stacking faults. Sawteeth-like structures are observed on the Zn-terminated polar (0001) side surface only. These surfaces are chemically active, while S-terminated
surfaces and non-polar surfaces are not. On these active surfaces, autocatalysed vapour–solid growth leads to the formation of the observed sawteeth.
