Nanofibers and Nanowires and Nanowires
37th European Conference and Exposition on Optical Communications, 2011Abstract (100 Word Limit): When its size goes down to the wavelength of the guided light, an optical nanofibre/nanowire exhibits interesting properties such as tight optical confinement, strong near-field interaction, abnormal dispersion, enhanced surface effects and excellent mechanical flexibilities, which opens opportunities for combining waveguide ...

We report the design and demonstration of nanowire temperature reporters. Metal alloys with tunable melting points were used to create nanowires in nanopores of anodic aluminum oxide using mechanical pressure injection. When exposed to temperature above their melting points, nanowires began to break up into disconnected shorter nanorods due to Rayleigh

The use of nanowires and nanowire structures as photodetectors is an emerging research topic. Despite the large amount of reports on nanowire photoresponse that appeared in the literature over the last decade, the mechanism leading to high photosensitivity and photoconductive gain in high aspect ratio nanostructures has been elucidated only recently ...

Microtubule‐Based Gold Nanowires and Nanowire Arrays
Small, 2008AbstractBiological structures are attractive as templates to form nanoscale architectures for electronics because of their dimensions and the ability to interact with inorganic materials. In this study, we report the fabrication and electrical properties of microtubule (MT)‐templated Au nanowires, and methods for assembling Au nanowire arrays based on ...

Rational design of nanowire solar cells: from single nanowire to nanowire arrays
Nanotechnology, 2019Abstract In this review, we report several rational designs of nanowire-based solar cells from single nanowire to nanowire arrays. Two methods of nanowires fabrication: via ‘top-down’ and ‘bottom-up’, and two types of configurations including axial and radial junction are presented for nanowire-based solar cells. To enhance absorption,

AbstractDifferent strategies for obtaining nanowires (NWs) with ferromagnetic properties using the molecular beam epitaxy (MBE) grown nanostructures combining GaAs and Mn were investigated. Four types of structures have been studied: (i) self‐catalyzed GaAs:Mn NWs grown at low temperatures on GaAs(100) substrates; (ii) GaAs:Mn NWs grown at high ...

Abstract The present chapter develops the theory of interband, intersubband, and excitonic optical processes for semiconductor QWRs, in the same line as in earlier two chapters. The simple rectangular structure and analytical methods are considered first, followed by semi-analytical theories for practical structures.

We experimentally demonstrate the directional emission of polarized light from single semiconductor nanowires. The directionality of this emission has been directly determined with Fourier microphotoluminescence measurements of vertically oriented InP nanowires.
