Fuzzy band structure of quantum dots by Bloch Orbital Expansion, unconventional insights into geometry-electronic structure relations
Zeger Hens, Jordi Llusar, Ivan Infante
The extension of ab-initio methods like density functional theory (DFT) to quantum dot (QD) geometries has enabled researchers to explore relationships between QD surface terminati…
Interfacial Reconstructions and Engineering in III-V@II-VI Core-Shell Quantum Dots
Jordi Llusar, Abdessamad El Adel, Luca De Trizio +3
In core/shell quantum dots (QDs), the interface between semiconductors of different chemical character largely determines their optoelectronic properties. In III-V/II-VI systems, t…
Vanishing quantum confinement enables bright and thermally excited multi-carrier emission from semiconductor nanocrystals
Tjom Arens, Sander J. W. Vonk, A. Willem Vlasblom +5
Recently, nanocrystals in the regime of vanishing quantum confinement-termed bulk nanocrystals (BNCs)-have demonstrated remarkable optical gain characteristics. While their high-po…
Direct observation of the exciton polaron by serial femtosecond crystallography on single CsPbBr quantum dots
Zhou Shen, Margarita Samoli, Onur Erdem +28
The outstanding opto-electronic properties of lead halide perovskites have been related to the formation of polarons. Nevertheless, the observation of the atomistic deformation bro…
