Leveraging on the unique solar light absorption behavior, chemical stability, and piezoelectric properties, nanostructured group-III-nitrides were utilized for implementing various renewable energy harvesting and conversion applications. By using different dimensional nanostructures, especially nanowires, and nanoporous membranes, this dissertation explored the practical applications in photocatalytic nitrogen reduction reaction, photocatalytic wastewater remediation, and flexible self-powered piezoelectric sensing.
