The fate of optical excitons in FAPbI3 nanocube superlattices
Alessandra Milloch, Umberto Filippi, Paolo Franceschini +8
Understanding the nature of the photoexcitation and ultrafast charge dynamics pathways in organic halide perovskite nanocubes and their aggregation into superlattices is key for th…
Ultrafast THz probe of photo-induced polarons in lead-halide perovskites
Eugenio Cinquanta, Daniele Meggiolaro, Silvia G. Motti +8
We study the nature of photo-excited charge carriers in CsPbBr3 nanocrystal thin films by ultrafast optical pump - THz probe spectroscopy. We observe a deviation from a pure Drude…
Contactless photo-induced carrier density control in nanocrystal MoS2 hybrids
Ilka Kriegel, Nicholas J. Borys, Kehao Zhang +9
The ultrathin nature of two-dimensional monolayer semiconductors yields optoelectronic properties which are highly responsive to changes in free-carrier density, making it imperati…
Confined optical phonon modes in polar tetrapod nanocrystals detected by resonant inelastic light scattering
R. Krahne, G. Chilla, C. Schueller +6
We investigated CdTe nanocrystal tetrapods of different sizes by resonant inelastic light scattering at room temperature and under cryogenic conditions. We observe a strongly reson…
