The tunneling conductance of an n-p-n junction initially increases upon lowering the temperature, while the coherence time of the electron-hole pairs is still less than their lifetime, but then drops back again when the coherence time exceeds the lifetime. This reentrance effect, known from diffusive conductors and ballistic quantum dots, provides a method to detect phase coherent Klein tunneling of electron-hole pairs.</dcterms:abstract> <dc:contributor>Ossipov, A.</dc:contributor> <dcterms:title>Reentrance effect in a graphene n-p-n junction coupled to a superconductor</dcterms:title> <dcterms:bibliographicCitation>First publ. in: Physical Review B 75 (2007), 241401(R), pp. 1-4</dcterms:bibliographicCitation> <dc:creator>Ossipov, A.</dc:creator> <dc:creator>Titov, M.</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:50:36Z</dcterms:available> </rdf:Description> </rdf:RDF>
