Theoretical insights into the role of lattice fluctuations on the excited behavior of lead halide perovskites
Yoonjae Park, Rohit Rana, Daniel Chabeda +2
Lead halide perovskites have been extensively studied as a class of materials with unique optoelectronic properties. A fundamental aspect that governs optical and electronic behavi…
Biexcitons are bound in CsPbBr3 Perovskite Nanocrystals
Yoonjae Park, David T. Limmer
We study the energetics of quasi-particle excitations in CsPbBr3 perovskite nanocrystals using path integral molecular dynamics simulations. Employing detailed molecular models, we…
Size-dependent lattice symmetry breaking determines the exciton fine structure of perovskite nanocrystals
Daniel Weinberg, Yoonjae Park, David T. Limmer +1
The ordering of optically bright and dark excitonic states in lead-halide perovskite nanocrystals has been a matter of some debate. It has been proposed that the unusually short ra…
Renormalization of excitonic properties by polar phonons
Yoonjae Park, David T. Limmer
We employ quasiparticle path integral molecular dynamics to study how the excitonic properties of model semiconductors are altered by electron-phonon coupling. We describe ways wit…
Up to 100 Faster Data-free Knowledge Distillation
Gongfan Fang, Kanya Mo, Xinchao Wang +4
Data-free knowledge distillation (DFKD) has recently been attracting increasing attention from research communities, attributed to its capability to compress a model only using syn…
