Fabrication of Pyramid Structure Substrate Utilized for Epitaxial Growth Free-Standing GaN
Metal−organic chemical vapor deposition (MOCVD)-grown GaN on sapphire substrate was etched by hot phosphoric acids. Pyramid structures were obtained in the N-polar face of the MOCVD−GaN. Details of the formation process and morphology of the structures were discussed. The crystal...
