Our experiments of transient photoinduced absorption suggest that charge carriers are formed with quantum yield of a few percent and that such species strongly affect the long-lived transient spectrum. Photogenerated charge carriers induce strong local electric fields that shift by the Stark effect the second subband exciton absorption in SWNTs, resulting in a characteristic derivative shape of the transient absorption spectra.</dcterms:abstract> <dc:creator>Späth, Florian</dc:creator> <dc:contributor>Späth, Florian</dc:contributor> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/52"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-01-21T07:48:17Z</dc:date> <dc:contributor>Cerullo, Giulio</dc:contributor> <dcterms:title>Ultrafast Charge Photogeneration in Semiconducting Carbon Nanotubes</dcterms:title> <dc:contributor>Brida, Daniele</dc:contributor> <dc:creator>Hertel, Tobias</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:issued>2013</dcterms:issued> <dc:contributor>Antognazza, Maria R.</dc:contributor> <dc:creator>Brida, Daniele</dc:creator> <dc:creator>Soavi, Giancarlo</dc:creator> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dc:creator>Lanzani, Guglielmo</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-01-21T07:48:17Z</dcterms:available> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Soavi, Giancarlo</dc:contributor> <dc:creator>Hefner, Timo</dc:creator> <dc:creator>Antognazza, Maria R.</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/52"/> <dc:contributor>Hertel, Tobias</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/29557"/> <dc:language>eng</dc:language> </rdf:Description> </rdf:RDF>
