Abstract:Understanding of the excitonic perspective on light-driven energy conversions is limited, particularly in higher excited states of excitons in 2D systems arising from nonlocal screening effects. Besides, the anisotropy in the sequence of excited exciton states (Rydberg Spectra) has been completely overlooked in the literature. This work presents a theoretical investigation of the anisotropic non-hydrogenic exciton dynamics in blue-AsP, systematically exploring the origin of the deviation from the conventional … Show more
The enhanced effect of electron-lattice interaction at high temperature proliferates long-lived dark excitons, facilitating efficient photocatalytic water splitting.
