Identification of a dominant mechanism for optical spin injection from a diluted magnetic semiconductor: Spin-conserving energy transfer via localized excitations
2005 (English)In: Physical Review B. Condensed Matter and Materials Physics, ISSN 1098-0121, E-ISSN 1550-235X, Vol. 72, no 7, 73206- p.Article in journal (Refereed) Published
We provide compelling experimental evidence for a spin-conserving energy-transfer process via localized excitations as being responsible for the observed optical spin injection in ZnMnSe ZnCdSe quantum structures. We show that such a process is common and inherent to a diluted magnetic semiconductor because of strong potential fluctuations. © 2005 The American Physical Society.
