Exciton-Phonon Coupling in Single Band-Gap Engineered ZnCdSe-Dot/CdS-Rod Nanocrystals
Florian Johst, Jannik Rebmann, Hans Werners +7
Exciton-phonon coupling limits the homogeneous emission linewidth of nanocrystals. Hence, a full understanding of it is crucial. In this work, we statistically investigate exciton-…
Influence of interface-driven strain on the spectral diffusion properties of core/shell CdSe/CdS dot/rod nanoparticles
Sven-Hendrik Lohmann, Philip Harder, Felix Bourier +3
By combining an atomistic valence-force field approach and calculations based on the effective-mass approximation we investigate the influence of strain effects on the band alignme…
Surface Charges on CdSe-Dot/CdS-Rod Nanocrystals: Measuring and Modeling the Diffusion of Exciton-Fluorescence Rates and Energies
Sven-Hendrik Lohmann, Christian Strelow, Alf Mews +1
By performing spectroscopic single-particle measurements at cryogenic temperatures over the course of hours we study %By performing spectroscopic longtime single-particle measureme…
Elementary excitations in charge-tunable InGaAs quantum dots studied by resonant Raman and resonant photoluminescence spectroscopy
Tim Köppen, Dennis Franz, Andreas Schramm +5
We report on resonant optical spectroscopy of self-assembled InGaAs quantum dots in which the number of electrons can accurately be tuned to N=0,1,2 by an external gate voltage. Po…
