Wet Etching: Controlling the Facet of ZnO during Wet Chemical Etching Its (0001¯) O‐Terminated Surface (Small 14/2020)

In article number 1906435, Qing Chen and co-workers obtain high-index {01 1 ¯ 3 ¯ } facets of ZnO during wet chemical etching of the (000 1 ¯ ) O-terminated surface of ZnO and also provide the direct experimental evidence of the micromasking mechanism for the hillocks formation via an in situ liquid cell transmission electron microscopy study.
