Facet-selective morphology-controlled remote epitaxy of ZnO microcrystals via wet chemical synthesis

Abstract We report on morphology-controlled remote epitaxy via hydrothermal growth of ZnO micro- and nanostructure crystals on graphene-coated GaN substrate. The morphology control is achieved to grow diverse morphologies of ZnO from nanowire to microdisk by changing additives of wet chemical soluti...
