Counterdirectional Exciton and Trion Motion in Applied Electric Field
Daniel Vaz, Yuanjun Guan, Qiaochu Wan +13
Charged excitonic complexes are central to the optoelectronic and many-body properties of semiconductors, yet their real-space transport dynamics remain largely unexplored. Here, w…

Light-Induced Electron Pairing in a Bilayer Structure
Qiaochu Wan, Daniel Vaz, Li Xiang +11
Previous experimental and theoretical work has given evidence of the existence of doubly charged exciton states in strongly screened bilayers of transition metal dichalcogenide (TM…

Measurement of exciton fraction of microcavity exciton-polaritons using transfer-matrix modeling
Jonathan Beaumariage, Zheng Sun, Hassan Alnatah +9
We present a careful calibration of the exciton fraction of polaritons in high- (), long-lifetime ( ps), GaAs/AlGaAs microcavities.This is a crucial para…
