With increasing number of oxygen atoms the lifetimes increase. This can be explained qualitatively by a metal-semiconductor transition occurring between the metal-like Al4 − cluster and the fully oxidized semiconductor-like Al4O6 − cluster. Long lifetimes of electron-hole excitations are characteristic for semiconductors, while in metals the strong interaction between the delocalized electrons causes short lifetimes.</dcterms:abstract> <dcterms:bibliographicCitation>Publ. in: Applied Physics A ; 100 (2010), 2. - pp. 431-436</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-09-06T06:14:50Z</dc:date> <dc:contributor>Proch, Sebastian</dc:contributor> <dc:language>eng</dc:language> <dc:contributor>Braun, Christian</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-09-06T06:14:50Z</dcterms:available> <dc:contributor>Ganteför, Gerd</dc:contributor> <dc:creator>Braun, Christian</dc:creator> <dc:creator>Koyasu, Kiichirou</dc:creator> <dc:contributor>Koyasu, Kiichirou</dc:contributor> <dcterms:title>The metal-semiconductor transition monitored by excited state lifetimes of Al4Om− clusters</dcterms:title> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/12482"/> </rdf:Description> </rdf:RDF>
