This is the accepted version of the work. The definitive version is published in Thin Solid Films, vol. 516(5), pp 844-846The 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 of 50 sccm and with a tungsten filament maintained at 1650ºC. The as-prepared powder varies in colour from yellowish to dark brown and is deposited on all surfaces inside the reaction chamber. The material is a highly porous agglomeration of nanoparticles of primary size in the order of 40 nm, with a narrow size distribution. The nanoparticles produced are mostly amorphous, hydrogenated and have a partially oxidized surface.enSilicon nanoparticlesPyrolysisAmorphous siliconCold substrateNanoparticle synthesisArticleScriba, M.
