Author:Scriba, Manfred R; Arendse, CJ; Harting, M; Britton, DTDate:Jan 2008The 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
Author:Thabethe, S; Arendse, CJ; Mwakikunga, Bonex WDate:Dec 2014Advanced core–shell FeSi@SiO(subx) nanowires are observed when FeCl(sub3) vapour is made to flow over a SiO(sub2)/Si substrate at 1100 degress C. The thickness of the SiO(subx) sheath (d0) is found to depend inversely as the period of time ...Read more
Author:Arendse, CJ; Malgas, G; Oliphant, CJ; Muller, TFG; Knoesen, DDate:2009The material properties of hydrogenated amorphous silicon (a-Si:H) have been known to change when exposed to elevated temperatures. In this work researchers report on the thermal stability of the optical band gap and structural disorder in ...Read more
