If the normal region is undoped, the excitation spectrum consists of neutral modes that propagate along the boundaries transporting energy but no charge. These Andreev modes are a coherent superposition of electron states from the conduction band and hole states from the valence band, coupled by specular Andreev reflection at the superconductor.</dcterms:abstract> <dcterms:isPartOf rdf:resource=""/> <dcterms:title>Excitation gap of a graphene channel with superconducting boundaries</dcterms:title> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:hasPart rdf:resource=""/> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> <dc:contributor>Titov, M.</dc:contributor> <dcterms:issued>2007</dcterms:issued> <dc:creator>Beenakker, Carlo W.
