Directed deposition of silicon nanowires using neopentasilane as precursor and gold as catalyst [PDF]

open access: yes, 2012
In this work the applicability of neopentasilane (Si(SiH3)4) as a precursor for the formation of silicon nanowires by using gold nanoparticles as a catalyst has been explored.

Pulsed PECVD growth of silicon nanowires on various substrates [PDF]

open access: yes, 2007
Silicon nanowires with high aspect ratio were grown using PPECVD and a gold catalyst on a variety of different substrates. The morphology of the nanowires was investigated for a range of crystalline silicon, glass, metal, ITO coated and amorphous silicon

Understanding of the Retarded Oxidation Effects in Silicon Nanostructures [PDF]

open access: yes, 2012
In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanostructures such as nanobeams, concave/convex nanorings and nanowires ...

The impacts of surface conditions on the vapor-liquid-solid growth of germanium nanowires on Si (100) substrate [PDF]

open access: yes, 2008
The impacts of surface conditions on the growth of Ge nanowires on a Si (100) substrate are discussed in detail. On SiO2-terminated Si substrates, high-density Ge nanowires can be easily grown. However, on H-terminated Si substrates, growing Ge nanowires

Cu-catalyzed Si-NWS grown on “carbon paper” as anodes for Li-ion cells [PDF]

open access: yes, 2019
The very high theoretical capacity of the silicon (4200mAh/g more than 10 times larger than graphite), environmental-friendly, abundant and low-cost, makes it a potential candidate to replace graphite in high energy density Li-ion batteries.

Modulation of Thermal Conductivity in Kinked Silicon Nanowires: Phonon Interchanging and Pinching Effects

open access: yes, 2013
We perform molecular dynamics simulations to investigate the reduction of the thermal conductivity by kinks in silicon nanowires. The reduction percentage can be as high as 70% at room temperature.
