## Abstract The cover picture refers to the Rapid Research Letter by Zhiming M. Wang et al. [1] and displays the nanostructure evolution during GaAs growth by droplet epitaxy. The two colored AFM images of 2 µm × 2 µm show the formation of GaAs nano‐crystals shaped like lighted candles and square‐h
## Abstract We report on Ga nano‐droplets on GaAs(100) that are not stable under arsenic flux. Spontaneous evolution in shape leads to many interesting GaAs nanostructures. GaAs nano‐crystals shaped like lighted candles and square‐holed round coins are observed under different growth conditions. Th
