Koudinov, A. V., Namozov, B. R., Kusrayev, Yu. G., Lee, S., Dobrowolska, M., Furdyna, J. K.
The magneto-optical inter-polarization conversions by a layer of quantum dots have been investigated. Various types of polarization response of the sample were observed as a function of external...
Suppression of electron spin relaxation in Mn-doped GaAs (2007)
Astakhov, G. V., Dzhioev, R. I., Kavokin, K. V., Korenev, V. L., Lazarev, M. V., Tkachuk, M. N., ...
We report a surprisingly long spin relaxation time of electrons in Mn-doped p-GaAs. The spin relaxation time scales with the optical pumping and increases from 12 ns in the dark to 160 ns upon...
Bound magnetic polarons in the very dilute regime (2007)
Kusrayev, Yu. G., Kavokin, K. V., Astakhov, G. V., Ossau, W., Molenkamp, L. W.
We study bound magnetic polarons (BMP) in a very diluted magnetic semiconductor CdMnTe by means of site selective spectroscopy. In zero magnetic field we detect a broad and asymmetric band with a...
Exciton spin decay modified by strong electron-hole exchange interaction (2006)
Astakhov, G. V., Koudinov, A. V., Kavokin, K. V., Gagis, I. S., Kusrayev, Yu. G., Ossau, W., ...
We study exciton spin decay in the regime of strong electron-hole exchange interaction. In this regime the electron spin precession is restricted within a sector formed by the external magnetic field...
Linear polarization of the photoluminescence of quantum wells (2006)
Koudinov, A. V., Averkiev, N. S., Kusrayev, Yu. G., Namozov, B. R., Zakharchenya, B. P., Wolverson, D., ...
The degree and orientation of the magnetic-field induced linear polarization of the photoluminescence from a wide range of heterostructures containing (Cd,Mn)Te quantum wells between (Cd,Mn,Mg)Te...
