Silicon Carbide nanowires are studied for the interesting properties of the material coupled with the unique features of quasi-one-dimensional nanostructures. The bulk synthesis of silicon carbide has been gaining increasing attention not only for the mechanical uses of the material, but also for the electronic properties.

Silicon nanowire photovoltaics
2008 33rd IEEE Photovolatic Specialists Conference, 2008Arrays of hundreds of parallel silicon nanowire p-n junction diodes, 20 nm in diameter and separated from each other by 14 nm, were fabricated using a variant of nanoimprint lithography. Bulk film diodes were also fabricated adjacent to the arrays as controls. Dark I–V curves from the nanowire arrays and bulk films suggest that performance is currently

Microelectronics International, 2014
Purpose– The purpose of this study is to present reports on fabrication of silicon (Si) nanowires (NWs). The study consists of microwire formation on silicon-on-insulator (SOI) that was fabricated using a top-down approach which involved conventional photolithography coupled with shallow anisotropic etching.Design/methodology/approach– A 5-inch p-type ...

Electric‐Driven Rotation of Silicon Nanowires and Silicon Nanowire Motors
Advanced Functional Materials, 2014In this work, the first highly controllable assembly and rotation of silicon nanowires and nanomotors in suspension are reported. Si and Si composite nanowires are fabricated with precisely controlled dimensions via colloidal assisted catalytic etching. The nanowires can be rotated with deterministic speed and chirality.

Desorption/Ionization on Silicon Nanowires
Analytical Chemistry, 2005Dense arrays of single-crystal silicon nanowires (SiNWs) have been used as a platform for laser desorption/ionization mass spectrometry of small molecules, peptides, protein digests, and endogenous and xenobiotic metabolites in biofluids. Sensitivity down to the attomole level has been achieved on the nanowire surfaces by optimizing laser energy ...

Since the discovery of carbon nanotubes by lijima [1] in 1991, one-dimensional (1D) nanomaterials including tubes, wires, cables and ribbons have attracted an explosive interest. A great deal of work has been done on exploring the various fundamental properties and potential applications of carbon nanotubes [2–6].

Pristine Semiconducting [110] Silicon Nanowires
Nano Letters, 2005We report results of ab initio calculations on silicon nanowires oriented along the [110] direction and show for the first time that these pristine silicon nanowires are indirect band gap semiconductors. The nanowires have bulk Si core and are bounded by two (100) and two (110) planes in lateral directions. The (100) planes are atomically reconstructed

Silicon nanowire-based solar cells
Nanotechnology, 2008The fabrication of silicon nanowire-based solar cells on silicon wafers and on multicrystalline silicon thin films on glass is described. The nanowires show a strong broadband optical absorption, which makes them an interesting candidate to serve as an absorber in solar cells.

Sawtooth Faceting in Silicon Nanowires
Physical Review Letters, 2005We observe in situ the vapor-liquid-solid (VLS) growth of Si nanowires, in UHV-CVD using Au catalyst. The nanowire sidewalls exhibit periodic sawtooth faceting, reflecting an oscillatory growth process. We interpret the facet alternation as resulting from the interplay of the geometry and surface energies of the wire and liquid droplet.
