Strain-driven spin mixing and dark-exciton recombination in a neutral Ni2+ doped quantum dot
K. E. Polczynska, S. Karouaz, W. Pacuski +1
We investigate the optical properties of neutral excitons in CdTe/ZnTe quantum dots containing a single Ni2+ ion. We show that the photoluminescence spectra provide a direct spectr…
Influence of local strain on the optical probing of a Ni spin in a charged self-assembled quantum dot
K. E. Polczynska, S. Karouaz, W. Pacuski +1
This study explores the optical properties of quantum dots doped with a Ni ion that interacts with a charged exciton. Systematic magneto-optical analysis reveals that the st…
Exciton-phonon coupling efficiency in CdSe quantum dots embedded in ZnSe nanowires
S. Bounouar, C. Morchutt, M. Elouneg-Jamroz +8
Exciton luminescence of a CdSe quantum dot (QD) inserted in a ZnSe nanowire is strongly influenced by the dark exciton states. Because of the small size of these QDs (2-5nm), excha…
Subnanosecond spectral diffusion of a single quantum dot in a nanowire
G. Sallen, A. Tribu, T. Aichele +7
We have studied spectral diffusion of the photoluminescence of a single CdSe quantum dot inserted in a ZnSe nanowire. We have measured the characteristic diffusion time as a functi…
