The experimental results are compared with theoretical calculations. The transient field is calculated with a drift-diffusion model. Our calculation of the dielectric function of GaAs includes the Coulomb coupling and the electric field. The resulting optical transmission changes are calculated with a transfer-matrix method. The theory predicts a modification of the Franz-Keldysh modulation due to the nonuniform field, in quantitative agreement with the experimental observations.</dcterms:abstract> <dc:creator>Hunsche, Stefan</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dc:contributor>Hunsche, Stefan</dc:contributor> <dc:creator>Kurz, Heinrich</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:contributor>Leo, Karl</dc:contributor> <dc:contributor>Kurz, Heinrich</dc:contributor> <dc:creator>Dekorsy, Thomas</dc:creator> <dc:contributor>Heesel, Heinrich</dc:contributor> <dcterms:issued>1993</dcterms:issued> <dc:language>eng</dc:language> <dc:contributor>Mikkelsen, Hakon</dc:contributor> <dc:creator>Mikkelsen, Hakon</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:53:26Z</dc:date> <dc:creator>Heesel, Heinrich</dc:creator> <dc:contributor>Dekorsy, Thomas</dc:contributor> <dc:format>application/pdf</dc:format> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:53:26Z</dcterms:available> <dc:creator>Leo, Karl</dc:creator> <dcterms:bibliographicCitation>First publ. in: Physical Review B 47 (1993), 23, pp. 16000-16003</dcterms:bibliographicCitation> <dcterms:title>Dynamics of electric field screening in a bulk GaAs modulator</dcterms:title> </rdf:Description> </rdf:RDF>
