Optoelectronic properties of single and array of 1-D III-nitride nanostructures: An approach to light-driven device and energy resourcing

Abstract

One dimensional (1-D) group III-nitride nanostructures are important components of optoelectronic devices owing to its unique feature of unidirectional carrier flow, and efficient electrical connectivity. The group III-nitride materials are attractive for the application as low power white and blue–green light sources provide a green and extended operational life. We discuss the luminescence phenomena observed in single or arrayed 1-D III-nitride nanostructures including quantum wells. The role of these 1-D nanostructures is critically reviewed in the field of ‘green’ energy generation, namely hydrogen source in fuel cells, the photoelectrochemical workhorse in renewable energy resourcing, and in solar cells.
