Journal ArticleDOI
Single-crystal gallium nitride nanotubes.
Joshua E. Goldberger,Rongrui He,Yanfeng Zhang,Sangkwon Lee,Haoquan Yan,Heon Jin Choi,Peidong Yang,Peidong Yang +7 more
TL;DR: An ‘epitaxial casting’ approach for the synthesis of single-crystal GaN nanotubes with inner diameters of 30–200 nm and wall thicknesses of 5–50nm is reported, applicable to many other semiconductor systems.
Journal ArticleDOI
Metalorganic Chemical Vapor Deposition Route to GaN Nanowires with Triangular Cross Sections
Tevye Kuykendall,Peter J. Pauzauskie,Sangkwon Lee,Yanfeng Zhang,Joshua E. Goldberger,Peidong Yang +5 more
TL;DR: In this article, high-quality gallium nitride nanowires have been synthesized via metal-initiated metalorganic chemical vapor deposition for the first time, and excellent substrate coverage was observed for wires prepared on silicon, c-plane, and a-plane sapphire substrates.
Journal ArticleDOI
Self-Organized GaN Quantum Wire UV Lasers
Heon Jin Choi,Justin C. Johnson,Rongrui He,Sangkwon Lee,Franklin Kim,Peter J. Pauzauskie,Joshua E. Goldberger,Richard J. Saykally,Peidong Yang +8 more
TL;DR: In this paper, a novel quantum-wire-in-optical-fiber (Qwof) nanostructure was obtained as a result of spontaneous Al−Ga−N phase separation at the nanometer scale in one dimension.
Journal ArticleDOI
