spelling Octagonal defects as the source of gap states in graphene semiconducting structuresPelc, MartaJaskólski, WłodzimierzAyuela, AndrésChico, LeonorTrabajo presentado al 42th "Jaszowiec" International School and Conference on the Physics of Semiconductors (Wisla-Polonia 2013).We study graphene nanoribbons and carbon nanotubes with divacancies, i.e., local defects composed of one octagon and a pair of pentagons. We show that the presence of divacancies leads to the appearance of gap states, which may act as acceptor or donor states. We explain the origin of those defect-localized states and prove that they are directly related to the zero-energy states of carbon ring forming the octagonal topological defect.This work was supported by the Polish National Science Center (grant DEC-2011/03/B/ST3/00091), the Spanish Ministry of Economy and Competitiveness (grant No. FIS2012-33521), the Basque Departamento de Educación and the University of the Basque Country (grant No. IT-366-07), the Basque Departamento de Industria and the Diputación Foral de Guipuzcoa under the ETORTEK program (NANO-IKER grant No. IE11-304).Peer ReviewedPolish Academy of SciencesNational Science Centre (Poland)Ministerio de Economía y Competitividad (España)Eusko JaurlaritzaEusko JaurlaritzaDiputación Foral de GuipúzcoaUniversidad del País Vasco2014201420132014info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/95151reponame:DIGITAL.CSIC.
