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…
Metal-free heteroatom doping of carbon nitride for enhanced photocatalytic hydrogen peroxide production
Eneko Sebastian-Garate, Bruna F. Gonçalves, Jordi Llusar +5
The photocatalytic production of hydrogen peroxide (HO) from water is a promising strategy for solar-to-chemical energy conversion. Herein, we investigate the effect of met…
Nanocrystals Heterostructures based on Halide Perovskites and Metal Sulfides
Nikolaos Livakas, Juliette Zito, Yurii P. Ivanov +4
We report the synthesis of nanocrystal heterostructures composed of CsPbCl3 and PbS domains sharing an epitaxial interface. We were able to promote the growth of a PbS domain (in c…
Improving the Stability of Colloidal CsPbBr3 Nanocrystals with an Alkylphosphonium Bromide as Surface Ligand Pair
Meenakshi Pegu, Hossein Roshan, Clara Otero-Martinez +9
In this study, we synthesised a phosphonium-based ligand, trimethyl(tetradecyl)phosphonium bromide (TTP-Br), and employed it in the post-synthesis surface treatment of Cs-oleate-ca…
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…
Exogenous Metal Cations in the Synthesis of CsPbBr3 Nanocrystals and their Interplay with Tertiary Amines
Zhanzhao Li, Luca Goldoni, Ye Wu +9
Current syntheses of CsPbBr3 halide perovskite nanocrystals (NCs) rely on over-stoichiometric amounts of Pb2+ precursors, resulting in unreacted lead ions at the end of the process…
