Exciton spin dynamics in spherical CdS quantum dots
P. Horodyska, P. Nemec, D. Sprinzl +3
Exciton spin dynamics in quasi-spherical CdS quantum dots is studied in detail experimentally and theoretically. Exciton states are calculated using the 6-band k.p Hamiltonian. It…
Systematic investigation of influence of n-type doping on electron spin dephasing in CdTe
D. Sprinzl, P. Horodyska, E. Belas +3
We used time-resolved Kerr rotation technique to study the electron spin coherence in a comprehensive set of bulk CdTe samples with various concentrations of electrons that were su…
Light-induced magnetization precession in GaMnAs
E. Rozkotova, P. Nemec, P. Horodyska +7
We report dynamics of the transient polar Kerr rotation (KR) and of the transient reflectivity induced by femtosecond laser pulses in ferromagnetic (Ga,Mn)As with no external magne…
Laser-induced Precession of Magnetization in GaMnAs
E. Rozkotova, P. Nemec, D. Sprinzl +7
We report on the photo-induced precession of the ferromagnetically coupled Mn spins in (Ga,Mn)As, which is observed even with no external magnetic field applied. We concentrate on…
Two-phonon assisted exciton spin relaxation due to exchange interaction in spherical quantum dots
P. Nahálková, D. Sprinzl, P. Malý +3
Spin relaxation in undoped quasi-spherical CdS quantum dots at zero magnetic fields is investigated using time- and polarization-resolved transient absorption measurements. Unlike…
