| Description |
In the present study, nanotextured surface protrusion induced superhydrophobicity in GaN microbelt is reported. The results show that along with nanometer-scale topographic features, the special air trapped nanocavities formed beneath the liquid droplet are solely responsible for the transition of superhydrophobicity having hydrophilic origin in GaN. The built-in nanocavities, ( ~ 80 nm in diameter) provide an ideal model for producing stable air trapped region. A calculation of shape of the meniscus at the interface of air and water in an isolated cavity correlates well with the macroscopic surface wetting behavior.
