Twist Angle Dependent Interlayer Exciton Lifetimes in van der Waals Heterostructures
Junho Choi, Matthias Florian, Alexander Steinhoff +15
In van der Waals (vdW) heterostructures formed by stacking two monolayers of transition metal dichalcogenides, multiple exciton resonances with highly tunable properties are formed…
Clustering with Fast, Automated and Reproducible assessment applied to longitudinal neural tracking
Hanlin Zhu, Xue Li, Liuyang Sun +5
Across many areas, from neural tracking to database entity resolution, manual assessment of clusters by human experts presents a bottleneck in rapid development of scalable and spe…
Moiré Potential Impedes Interlayer Exciton Diffusion in van der Waals Heterostructures
Junho Choi, Wei-Ting Hsu, Li-Syuan Lu +16
The properties of van der Waals (vdW) heterostructures are drastically altered by a tunable moiré superlattice arising from periodic variations of atomic alignment between the laye…
Routing Valley Excitons in a Monolayer MoS2 with a Metasurface
Liuyang Sun, Chun-Yuan Wang, Alexandr Krasnok +8
Excitons in monolayer transition metal dichalcogenides (TMDs) are formed at K and K' points at the boundary of the Brillouin zone. They acquire a valley degree of freedom, which ma…
Impact of Grain Boundaries on Efficiency and Stability of Organic-Inorganic Trihalide Perovskites
Zhaodong Chu, Mengjin Yang, Philip Schulz +7
Organic-inorganic perovskite solar cells have attracted tremendous attention because of their remarkably high power conversion efficiencies (PCEs). To further improve the device pe…
Direct Measurement of Exciton Valley Coherence in Monolayer WSe
Kai Hao, Galan Moody, Fengcheng Wu +7
In crystals, energy band extrema in momentum space can be identified by their valley index. The internal quantum degree of freedom associated with valley pseudospin indices can act…
