Therefore, the determination of injection-dependent recombination properties from such measurements was previously found to require integration over the entire injection range. Recent investigations of the phase shift between a time-modulated irradiation of silicon samples and excess carrier density reveal a striking analogy to the above findings: the phase shift is greater than the actual effective carrier lifetime in the case of a positive derivative of lifetime with respect to excess carrier density, and vice versa. This work attempts to rearrange the mentioned previous findings in a quantitative theoretical description of light-biased dynamic measurements of effective carrier lifetime. Both light-biased differential lifetime measurements as well as harmonically time-modulated methods without additional bias light are shown to represent a limiting case in a general treatment of light-biased dynamic lifetime measurements derived here. Finally, we sketch a way to obtain actual recombination properties from differential measurements-referred to as a differential-to-actual (d2a) lifetime analysis, which does not require integration over the entire injection range.</dcterms:abstract> <dc:contributor>Warta, Wilhelm</dc:contributor> <dc:contributor>Glunz, Stefan W.</dc:contributor> <dc:contributor>Giesecke, Johannes A.</dc:contributor> <dcterms:bibliographicCitation>Journal of applied physics ; 113 (2013), 7. - 073706</dcterms:bibliographicCitation> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-01-28T12:16:07Z</dc:date> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-01-28T12:16:07Z</dcterms:available> <dc:creator>Glunz, Stefan W.</dc:creator> <dcterms:title>Understanding and resolving the discrepancy between differential and actual minority carrier lifetime</dcterms:title> <dc:creator>Warta, Wilhelm</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/25063"/> <dc:rights>deposit-license</dc:rights> <dc:creator>Giesecke, Johannes A.</dc:creator> </rdf:Description> </rdf:RDF>
