Heitmann, D. Heyn, Ch. Schüller, Christian Bichler, M. Wegscheider, Werner Erscheinungsjahr: 2002 Medientyp: Text Beschreibung: We report the observation of a strong anomaly in the magnetic-field dispersion of negatively charged excitons in dilute two-dimensional electron systems. The anomaly exists in an intermediate density range around 1 × 1011 cm-2, and at temperatures T Lizenz: info:eu-repo/semantics/closedAccess Quellsystem: Forschungsinformationssystem der UHH Interne Metadaten Quelldatensatz oai:www.edit.fis.uni-hamburg.de:publications/629f6e14-a5f0-4525-a2a2-aea537628d3e
