GaN epitaxial layer over growth method

Wang-Nang Wang (Inventor)

Research output: Patent


Nanostructures formed on a surface of a substrate are used as nucleation sites for epitaxial overgrowth of bulk gallium nitride semiconductor crystals including device layers. Nanocolumn nucleation sites are formed using a nanostructured mask on the substrate by etching the substrate or by selective area growth in the mask openings. The epitaxial growth method is used for fabricating gallium nitride optoelectronic devices.
