Quantum dot (QD) assemblies are nanostructured networks made from aggregatesof QDs and feature improved charge and energy transfer efficiencies compared todiscrete QDs. Using first-principles many-body perturbation theory, wesystematically compare the electronic and optical properties of two types ofCdS QD assemblies that have been experimentally investigated: QD gels, whereindividual QDs are covalently connected via di- or poly-sulfide bonds, and QDnanocrystals, where individual QDs are bound via van der Waals interactions.Our work illustrates how the electronic, excitonic, and optical propertiesevolve when discrete QDs are assembled into 1D, 2D, and 3D gels andnanocrystals, as well as how the one-body and many-body interactions in thesesystems impact the trends as the dimensionality of the assembly increases.Furthermore, our work reveals the crucial role of the covalent di- orpoly-sulfide bonds in the localization of the excitons, which highlights thedifference between QD gels and QD nanocrystals.
