Electron transfer and cascade relaxation dynamics of graphene quantum dots/MoS2 monolayer mixed-dimensional van der Waals heterostructures
Hangyong Shan,Ying Yu,Rui Zhang,Runtan Cheng,Dong Zhang,Yang Luo,Xingli Wang,Bowen Li,Shuai Zu,Feng Lin,Zheng Liu,Kai Chang,Zheyu Fang +12 more
TL;DR: In this article, the biphasic electron injection model and modified rate equations are employed to quantitatively solve interfacial transfer rates of mixed-dimensional VdW heterostructures.
Phonon scattering and exciton localization: molding exciton flux in two dimensional disorder energy landscape
Pengfei Qi,Pengfei Qi,Yang Luo,Beibei Shi,Wei Li,Donglin Liu,Liheng Zheng,Zhixin Liu,Yanglong Hou,Zheyu Fang +9 more
TL;DR: In this paper, an optimized scheme for exciton diffusion and relaxation dominated by phonon scattering and disorder potentials in WSe2 monolayers is presented. But, the experimental results show that the excitons tend to be localized by disorder potential, and the effective diffusion coefficient is enhanced by ∼200% at 280 k.

Journal ArticleDOI
Substrate-mediated charge transfer plasmons in simple and complex nanoparticle clusters
Yumin Wang,Ziwei Li,Ke Zhao,Ali Sobhani,Xing Zhu,Zheyu Fang,Zheyu Fang,Naomi J. Halas,Naomi J. Halas +8 more
TL;DR: A mixed charge transfer-dipole mode is observed, where charge transfer is induced on the outer nanoparticles, establishing an opposing dipole on the intervening central particles, resulting in a strongly damped far field response.
Journal ArticleDOI
Enhanced optical performance of multifocal metalens with conic shapes
TL;DR: It is shown that the defects of the traditional method can be overcome by designing a metalens with conic shapes (the ellipse and the hyperbola), which could improve the imaging performance and substantially decrease the background noise of multifocal metalenses.
