Abstract
AbstractSilica nanowires were synthesized from mixture monosilane with hydrogen by gas‐jet electron beam plasma chemical vapor deposition method for the first time. The synthesis was carried out on silicon substrate with up to micrometer‐sized particles of Sn catalyst. SEM observations show that this method provides different morphology of the nanowires and catalyst. Oriented arrays of silica nanowires bunches (microropes) were synthesized in the area corresponding to the mixture jet axis. Cocoons‐like, bamboo‐like, and jellyfish‐like morphology was observed in the area corresponding to periphery of the jet. Probably there was realised vapor‐liquid‐solid (VLS) growth mechanism, where multiple nanowires grow simultaneously from the surface of one catalyst drop. The growth rate of the microropes is about 25 nm/s at synthesis temperature 330 °C. Possible growth model has been suggested in order to explain the results. (© 2014 WILEY‐VCH Verlag GmbH & Co.
