In femtosecond time-resolved studies, a strong increase of the coherent LO phonon amplitudes is observed when the Bloch oscillations are subsequently tuned into resonance with the different optical phonon modes of the ternary semiconductor materials. In a narrow-well superlattice where electronic minibands are energetically shifted close to the confining barrier potential, the phonon amplitudes are asymmetrically enhanced on the high-frequency edge of the resonance. Here, at high electric fields, field induced tunneling into above-barrier continuum states leads to a rapid dephasing of Bloch oscillations. The associated polarization change provides an additional excitation process for coherent LO phonons.</dcterms:abstract> <dc:creator>Kurz, Heinrich</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:56:43Z</dc:date> <dc:rights>deposit-license</dc:rights> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9453"/> <dc:contributor>Först, Michael</dc:contributor> <dc:creator>Leavitt, Richard P.</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:56:43Z</dcterms:available> <dcterms:title>Well-width dependence of coupled Bloch-phonon oscillations in biased InGaAs/InAlAs superlattices</dcterms:title> <dc:format>application/pdf</dc:format> <dcterms:bibliographicCitation>First publ. in: First publ. in: Physica Status Solidi / C, Vol. 1 (2004), 11, pp. 2702-2705</dcterms:bibliographicCitation> <dc:creator>Dekorsy, Thomas</dc:creator> <dc:contributor>Leavitt, Richard P.</dc:contributor> <dcterms:issued>2004</dcterms:issued> <dc:language>eng</dc:language> <dc:contributor>Kurz, Heinrich</dc:contributor> </rdf:Description> </rdf:RDF>
