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…
Bose condensation of upper-branch exciton-polaritons in a transferrable microcavity
Xingzhou Chen, Hassan Alnatah, Danqun Mao +9
Exciton-polaritons are composite bosonic quasiparticles arising from the strong coupling of excitonic transitions and optical modes. Exciton-polaritons have triggered wide explorat…
Photoluminescence switching in a two-dimensional atomic crystal
Zheng Sun, Ke Xu, Chang Liu +5
Two-dimensional materials are an emerging class of new materials with a wide range of electrical and optical properties and potential applications. Single-layer structures of semic…
Dynamics of spin polarization in tilted polariton rings
S. Mukherjee, V. K. Kozin, A. V. Nalitov +9
We have observed the effect of pseudo magnetic field originating from the polaritonic analog of spin-orbit coupling (TETM splitting) on a polariton condensate in a ring-shaped m…
Observation of the Interlayer Exciton Gases in WSe -p: WSe Heterostructures
Zheng Sun, Jonathan Beaumariage, Qingrui Cao +4
Interlayer excitons (IXs) possess a much longer lifetime than intralayer excitons due to the spatial separation of the electrons and holes; hence, they have been pursued to create…
Observation of Non-equilibrium Motion and Equilibration in Polariton Rings
S. Mukherjee, D. M. Myers, R. G. Lena +8
We present a study of the macroscopic dynamics of a polariton condensate formed by non-resonant optical excitation in a quasi-one-dimensional ring-shaped microcavity. The presence…
