Single-photon superradiance in individual cesium lead halide quantum dots
(2023)Research SquareThe brightness of an emitter is ultimately described by Fermi’s golden rule, with a radiative rate proportional to its oscillator strength times the local density of photonic states (LDOS). Since the oscillator strength is an intrinsic material property, the quest for ever brighter emission has relied on LDOS engineering, via dielectric or plasmonic resonators1,2. In contrast, a much less explored avenue is to boost the oscillator strength, ...Working Paper -
Scaling of Hybrid QDs-Graphene Photodetectors to Subwavelength Dimension
(2023)arXivEmerging colloidal quantum dot (cQD) photodetectors currently challenge established state-of-the-art infrared photodetectors in response speed, spectral tunability, simplicity of solution processable fabrication, and integration onto curved or flexible substrates. Hybrid phototransistors based on 2D materials and cQDs, in particular, are promising due to their inherent photogain enabling direct photosignal enhancement. The photogain is ...Working Paper
