The low and core-loss regions have been analyzed to provide by the same technique a combined information about chemical bonding in the different materials in the sample and the electronic properties of individual BN-NTs. In particular, we deduce an optical gap value of about 5.8 eV for single walled nanotubes, which is independent on diameter. 000060909 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000060909 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060909 700__ $$aStephan, O. 000060909 700__ $$aKociak, M. 000060909 700__ $$aTaverna, D. 000060909 700__ $$aColliex, C. 000060909 700__ $$aRubio, A. 000060909 700__ $$aLoiseau, A. 000060909 773__ $$g723, 1 (2004), 293-297$$pAIP conf. proc.$$tAIP conference proceedings$$x0094-243X 000060909 8564_ $$s2145456$$uhttps://zaguan.unizar.es/record/60909/files/texto_completo.pdf$$yVersión publicada 000060909 8564_ $$s79145$$uhttps://zaguan.unizar.es/record/60909/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000060909 909CO $$ooai:zaguan.unizar.es:60909$$particulos$$pdriver 000060909 951__ $$a2017-04-05-14:45:43 000060909 980__ $$aARTICLE
