Micro/Nano hierarchical peony like Al doped ZnO superhydrophobic film: The guidi

In this communication, we present a versatile and controllable strategy for formation of superhydrophobic micro/nano hierarchical Al doped ZnO (AZO) films with a water contact angle (CA) of 170 +/- 4 degrees. This strategy involves a two-step layer-by-layer process employing an atomic layer depositi
