Long-lived electron spin coherence in CdSe/ZnSSe self-assembled quantum dots
M. Syperek, D. R. Yakovlev, I. A. Yugova +6
The electron spin coherence in n-doped and undoped, self-assembled CdSe/Zn(S,Se) quantum dots has been studied by time-resolved pump-probe Kerr rotation. Long-lived spin coherence…
Photoluminescence investigations of 2D hole Landau levels in p-type single Al_{x}Ga_{1-x}As/GaAs heterostructures
M. Kubisa, L. Bryja, K. Ryczko +7
We study the energy structure of two-dimensional holes in p-type single Al_{1-x}Ga_{x}As/GaAs heterojunctions under a perpendicular magnetic field. Photoluminescence measurments wi…
Exciton lifetime and emission polarization dispersion in strongly in-plane asymmetric nanostructures
M. GaweÅczyk, M. Syperek, A. MaryÅski +8
We present experimental and theoretical investigation of exciton recombination dynamics and the related polarization of emission in highly in-plane asymmetric nanostructures. Consi…
On weak generalized stability and (c,d)-pseudostable random variables via functional equations
W. Jarczyk, J. Misiewicz
In this paper we give a first attempt to define and study stable distributions with respect to the weak generalized convolution, focusing our attention on the symmetric weakly stab…
Strongly temperature-dependent recombination kinetics of a negatively charged exciton in asymmetric quantum dots at 1.55 μm
Å. Dusanowski, M. GaweÅczyk, J. Misiewicz +3
We report on strongly temperature-dependent kinetics of negatively charged carrier complexes in asymmetric InAs/AlGaInAs/InP quantum dots (dashes) emitting at telecom wavelengths.…
Carrier trapping and luminescence polarization in quantum dashes
A. MusiaÅ, P. Kaczmarkiewicz, G. SÄk +6
We study experimentally and theoretically polarization-dependent luminescence from an ensemble of quantum-dot-like nanostructures with a very large in-plane shape anisotropy (quant…
Exciton spin relaxation in InAs/InGaAlAs/InP(001) quantum dashes emitting near 1.55 μm
M. Syperek, Å. Dusanowski, M. GaweÅczyk +5
Exciton spin and related optical polarization in self-assembled InAs/InGaAlAs/InP(001) quantum dashes emitting at 1.55 μm are investigated by means of p…
Spin coherence of holes in GaAs/AlGaAs quantum wells
M. Syperek, D. R. Yakovlev, A. Greilich +4
The carrier spin coherence in a p-doped GaAs/(Al,Ga)As quantum well with a diluted hole gas has been studied by picosecond pump-probe Kerr rotation with an in-plane magnetic field.…
