Spin dynamics and magnetic-field-induced polarization of excitons in ultrathin GaAs/AlAs quantum wells with indirect band gap and type-II band alignment
T. S. Shamirzaev, J. Rautert, D. R. Yakovlev +5
The exciton spin dynamics are investigated both experimentally and theoretically in two-monolayer-thick GaAs/AlAs quantum wells with an indirect band gap and a type-II band alignme…
Observation of three-particle complexes in WS monolayers
J. Jadczak, J. Kutrowska-Girzycka, P. Kapuscinski +6
Atomically thin semiconducting transition-metal dichalcogenides provide novel insights into the physics of many-body effects mediated by Coulomb interactions. Here, we report on te…
Anisotropies in the linear polarization of vacancy photoluminescence in diamond induced by crystal rotations and strong magnetic fields
D. Braukmann, V. P. Popov, E. R. Glaser +3
We study the linear polarization properties of the photoluminescence of the neutral and negatively charged nitrogen vacancies and neutral vacancies in diamond crystals as function…
Exciton and trion dynamics in atomically thin MoSe2 and WSe2: effect of localization
D. Schmidt, T. Godde, J. Schmutzler +9
We present a detailed investigation of the exciton and trion dynamics in naturally doped MoSe2 and WSe2 single atomic layers as a function of temperature in the range 10-300K under…
Optical orientation of hole magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells
E. A. Zhukov, Yu. G. Kusrayev, K. V. Kavokin +8
The optically induced spin polarization in (Cd,Mn)Te/(Cd,Mn,Mg)Te diluted-magnetic-semiconductor quantum wells is investigated by means of picosecond pump-probe Kerr rotation. At 1…
