WebFeb 15, 2024 · The final stage of the dewetting process, in which irregularly-shaped islands reorganize into more favorable configurations, is crucial in terms of determining nanostructure faceting. For a free-standing metal nanostructure, the equilibrium configuration, commonly referred to as the Wulff shape, is the shape which minimizes … Webelectro-dewetting. Li and colleagues’ work might also have implications for fundamental research. Standard wetting theories9 are equilibrium theories that are based on energy minimization. However, the need for a permanent electric current in electro-dewetting demonstrates that the microscopic origin of this mechanism
