Exciton fine structure in CdSe nanoplatelets using a quasi-2D screened configuration-interaction framework
Sumanti Patra, Gabriel Bester
We compute exciton binding energies and fine-structure splittings in CdSe nanoplatelets with two zincblende geometries and one wurtzite geometry, finding that the wurtzite structur…

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-…

Empirical Band-Gap Correction for LDA-Derived Atomic Effective Pseudopotentials
Surender Kumar, Hanh Bui, Gabriel Bester
Atomic effective pseudopotentials enable atomistic calculations at the level of accuracy of density functional theory for semiconductor nanostructures with up to fifty thousand ato…
