Composition and crystallinity of silicon nanoparticles synthesised by hot wire thermal catalytic pyrolysis at different pressures

Author: Scriba, Manfred R ; Britton, DT ; Arendse, C ; van Staden, MJ ; Härting, M Date: Apr 2009 The effect of pressure on the structure and composition of silicon nanoparticles synthesized by hot wire thermal catalytic pyrolysis (HW-TCP) of pure silane has been investigated. Light brown powders were produced at silane pressures of 10 ... Read more
Electrically active, doped monocrystalline silicon nanoparticles produced by hot wire thermal catalytic pyrolysis

Author: Scriba, Manfred R ; Britton, DT ; Härting, M Date: May 2011 Doped silicon nanoparticles have successfully been produced by hot wire thermal catalytic pyrolysis at 40 mbar and a filament temperature of 1800 °C, using a mixture of silane and diborane or phosphine. All particles are monocrystalline with ... Read more
Hot wire and spark pyrolysis as simple new routes to silicon nanoparticle synthesis

Author: Scriba, Manfred R ; Britton, DT ; Härting, M Date: Nov 2012 Monocrystalline silicon nanoparticles with a mean diameter of between 30 and 40 nm have been synthesised by hot wire thermal catalytic and spark pyrolysis at a pressure of 40 and 80 mbar respectively. For the production a mixture of the ... Read more
Hot-wire synthesis of Si nanoparticles

Author: Scriba, Manfred R ; Arendse, CJ ; Harting, M ; Britton, DT Date: Jan 2008 The viability of producing silicon nanoparticles using the HWCVD process is investigated. A system is assembled and particles are produced from silane at pressures between 0.2 – 48 mbar, with hydrogen dilutions of 0-80%, at a total flow rate ... Read more
Thermal stability of hot-wire deposited amorphous silicon

Author: Arendse, CJ ; Knoesen, D ; Britton, DT Date: Apr 2006 The material properties of hydrogenated amorphous silicon (a-Si:H) have been known to change when exposed to elevated temperatures. In this work the authors report on the thermal stability of the structural disorder, hydrogen content and ... Read more
Topological investigation of electronic silicon nanoparticulate aggregates using ultra-small-angle X-ray scattering

Author: Jonah, EO ; Britton, DT ; Beaucage, P ; Rai, DK ; Beaucage, G ; Magunje, B ; Ilavsky, J ; Scriba, Manfred R ; Harting, M Date: Oct 2012 The network topology of two types of silicon nanoparticles, produced by high energy milling and pyrolysis of silane, in layers deposited from inks on permeable and impermeable substrates has been quantitatively characterized using ultra-small-angle ...
