Purcell-enhanced single-photon generation from CsPbBr quantum dots in in-situ selected Laguerre-Gaussian modes
Virginia Oddi, Darius Urbonas, Etsuki Kobiyama +9
Single photons in Laguerre-Gaussian (LG) beams, which carry orbital angular momentum (OAM), could enable more robust and efficient photonic quantum communication and information pr…
Radiation-Triggered Superfluorescent Scintillation in Quantum-Ordered Perovskite Nanocrystal Superlattices
Matteo L. Zaffalon, Andrea Fratelli, Taras Sekh +8
Superfluorescence, a cooperative emission phenomenon arising from the coherent coupling of excited dipoles, has historically been observed under optical excitation in carefully eng…
Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
Perovskite nanocrystal self-assemblies in 3D hollow templates
Etsuki Kobiyama, Darius Urbonas, Maryna I. Bodnarchuk +7
Highly ordered nanocrystal (NC) assemblies, namely superlattices (SLs), have been investigated as novel building blocks of optical and optoelectronic devices due to their unique pr…
Phonon-driven wavefunction localization promotes room-temperature, pure single-photon emission in large organic-inorganic lead-halide quantum dots
Leon G. Feld, Simon C. Boehme, Sebastian Sabisch +13
In lead halide perovskites (APbX3), the effect of the A-site cation on optical and electronic properties has initially been thought to be marginal. Yet, evidence of beneficial effe…
Ultrafast Vibrational Control of Hybrid Perovskite Devices Reveals the Influence of the Organic Cation on Electronic Dynamics
Nathaniel. P. Gallop, Dmitry R. Maslennikov, Katelyn P. Goetz +10
Vibrational control (VC) of photochemistry through the optical stimulation of structural dynamics is a nascent concept only recently demonstrated for model molecules in solution. E…
Dark-Bright Exciton Splitting Dominates Low-Temperature Diffusion in Halide Perovskite Nanocrystal Assemblies
Andreas J. Bornschlegl, Michael F. Lichtenegger, Leo Luber +4
Semiconductor nanocrystals could replace conventional bulk materials completely in displays and light-emitting diodes. Exciton transport dominates over charge carrier transport for…
Direct observation of ultrafast lattice distortions during exciton-polaron formation in lead-halide perovskite nanocrystals
Hélène Seiler, Daniela Zahn, Victoria C. A. Taylor +4
The microscopic origin of slow carrier cooling in lead-halide perovskites remains debated, and has direct implications for applications. Slow carrier cooling has been attributed to…
Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
Kinetic modelling of carrier cooling in lead halide perovskite materials
Thomas R. Hopper, Ahhyun Jeong, Andrei Gorodetsky +6
The relaxation of high-energy "hot" carriers in semiconductors is known to involve the redistribution of energy between (i) hot and cold carriers and (ii) hot carriers and phonons.…
High-resolution remote thermography using luminescent low-dimensional tin-halide perovskites
Sergii Yakunin, Bogdan M. Benin, Yevhen Shynkarenko +6
While metal-halide perovskites have recently revolutionized research in optoelectronics through a unique combination of performance and synthetic simplicity, their low-dimensional…
Superfluorescence from Lead Halide Perovskite Quantum Dot Superlattices
Gabriele Rainò, Michael A. Becker, Maryna I. Bodnarchuk +3
An ensemble of emitters can behave significantly different from its individual constituents when interacting coherently via a common light field. After excitation, collective coupl…
