A droplet depositing on a solid substrate leads to the wetting phenomenon, such as dew on plant leaves. On an ideally smooth substrate, the classic Young’s law has been employed to describe the wetting effect. However, no real substrate is ideally smooth at the microscale. Given this fact, we introd…
