Micromotors driven by UV light based on advanced hybrid GaN/ZnO nanoarchitectured microtubes

Abstract

Functional microstructures with designed hierarchical and complex morphologies and large free active surfaces based on novel hybrid nanoarchitectured GaN/ZnO microtubes with an outer hydrophobic GaN surface and an inner hydrophilic surface of chemically stabilized ZnO decorated by solid solution (Ga1–xZnx)(N1–xOx) NWs, which are terminated by co-catalyst AuGa-alloy nanodots have been developed and characterized.
