Biexcitons in CdSe nanoplatelets: geometry, binding energy and radiative rate
Royal Society of Chemistry (2022-05-13)Biexciton properties in semiconductor nanostructures are highly sensitive to quantum confinement, relative electron–hole masses, dielectric environment and Coulomb correlations. Here we present a variational Quantum Monte ... -
CdSe/CdS/CdTe Core/Barrier/Crown Nanoplatelets: Synthesis, Optoelectronic Properties, and Multiphoton Fluorescence Upconversion
American Chemical Society (2020-04-10)Colloidal two-dimensional (2D) nanoplatelet heterostructures are particularly interesting as they combine strong confinement of excitons in 2D materials with a wide range of possible semiconductor junctions due to a ... -
Shell filling and paramagnetism in few-electron colloidal nanoplatelets
American Physical Society (2022-08-05)Colloidal semiconductor nanoplatelets are excellent optical emitters, which combine a quasi-2D structure with strong in-plane Coulomb interactions. Here, we go beyond the photoexcitation regime and investigate theoretically ... -
Tuning intraband and interband transition rates via excitonic correlation in low-dimensional semiconductors
ACS Publications (2018-08)We show that electron-hole correlation can be used to tune interband and intra- band optical transition rates in semiconductor nanostructures with at least one weakly confined direction. The valence-to-conduction band ... -
Visible and Infrared Nanocrystal-Based Light Modulator with CMOS Compatible Bias Operation
American Chemical Society (2023-02-15)Nanocrystals are now established light sources, and as synthesis and device integration have gained maturity, new functionalities can now be considered. So far, the emitted light from a nanocrystal population remains mostly ...
