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…
