Public ISBD [article]  inActa materialia > Vol. 58 N° 8 (Mai 2010) . - pp. 3068–3072 Titre : Broadband anti-reflection and enhanced field emission from catalyst-free grown small-sized ITO nanowires at a low temperature Type de document : texte imprimé Auteurs : Neng Wan, Auteur ; Jun Xu, Auteur ; Guran Chen, Auteur Année de publication : 2011 Article en page(s) : pp. 3068–3072 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : ITO Nanostructure e-Beam evaporation Field emission Anti-reflection Résumé : Small-sized indium tin oxide (ITO) nanowires were fabricated using the electron beam evaporation (EBE) technique at low temperature (∼150 °C) without adding any catalyst. The ITO nanowires have a typical diameter of around 10 nm and a length of more than 100 nm, with body-centered cubic crystal structures that grow along the 〈1 0 0〉 directions, as revealed by transmission electron microscopy. The growth mechanism of the branched ITO nanowires was found to be a vapor–solid process. The nanowire films show a broadband anti-reflection property due to the graded refraction index from the film surface to the substrate. Enhanced field emission properties with a low turn-on electric field and a high field enhancement factor were also observed in the ITO nanowires.
