Homogeneous All-Inorganic Perovskite Films via High-Pressure Recrystallization
Asma Miled, Trong Tam Nguyen, Anh Vui Nguyen +13
Metal halide perovskites are promising materials for optoelectronic applications owing to their outstanding optical and electronic properties. Among them, all-inorganic perovskites…
Collective Fluorescence of Graphene Quantum Dots on a surface
Hugo Levy-Falk, Suman Sarkar, Thanh Trung Huynh +10
This study explores the organization of graphene quantum dots on the surface of monocrystalline halide perovskite. We show that graphene quantum dots tends to aggregate on the surf…
THz-Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites
Joanna M. Urban, Michael S. Spencer, Maximilian Frenzel +10
Metal-halide perovskites (MHPs) emerged as a family of novel semiconductors with outstanding optoelectronic properties for applications in photovoltaics and light emission. Recentl…
Long-range ballistic propagation of 80-excitonic-fraction polaritons in a perovskite metasurface at room temperature
Nguyen Ha My Dang, Simone Zanotti, Emmanuel Drouard +6
Exciton-polaritons, hybrid light-matter elementary excitations arising from the strong coupling regime between excitons in semiconductors and photons in photonic nanostructures, of…
Nanoimprinted Exciton-Polaritons Metasurfaces: Cost-Effective, Large-Scale, High Homogeneity, and Room Temperature Operation
Nguyen Ha My Dang, Paul Bouteyre, Gaëlle Trippé-Allard +5
Exciton-polaritons represent a promising platform that combines the strengths of both photonic and electronic systems for future optoelectronic devices. However, their application…
