Accelerating dynamic simulations of photoexcited materials and their evolution by electron-informed machine learning
Yunzhe Jia, Fankai Xie, Yunfei Bai +3
Nonadiabatic coupled electron-nuclear dynamics upon electronic excitation underpin the microscopic mechanism and rational modulation of diverse photoinduced functional phenomena in…
Observation of quasi-steady dark excitons and gap phase in a doped semiconductor
Shangkun Mo, Yunfei Bai, Chunlong Wu +16
Exciton plays an important role in optics and optics-related behaviors and leads to novel correlated phases like charge order, exciton insulator, and exciton-polariton condensation…
Intrinsic exciton transport and recombination in single-crystal lead bromide perovskite
Zhixuan Bi, Yunfei Bai, Ying Shi +13
Photogenerated carrier transport and recombination in metal halide perovskites are critical to device performance. Despite considerable efforts, sample quality issues and measureme…
Ab initio self-trapped excitons
Yunfei Bai, Yaxian Wang, Sheng Meng
We propose a new formalism and an effective computational framework to study self-trapped excitons (STE) in insulators and semiconductors from first principles. Using the many-body…
