Gallium Nitride Nanowires Based Nanogenerators and Light-Emitting Diodes

Abstract:
Single crystal n-type GaN nanowires have been grown epitaxially on aMg doped p-type GaN substrate.Piezoelectric nanogneratorsbased onthe GaN nanowires areinvestigated by a conductive AFM, andthe results showedan outputpower density nearly 12.5mW/m2.The luminous LEDmodules based on n-GaN nanowires/p-GaN substrate have been fabricated. CCD imagesof the lighted LED and the correspondingelectroluminescencespectra arerecorded at aforward bias. Moreover, the GaNnanowiresLED can be lit up by the power provided by a ZnO nanowire based nanogenerator, demonstrating a self-powered LED using wurtzite structured nanomaterials.
