Trion Valley Coherence in Monolayer Semiconductors
Kai Hao, Lixiang Xu, Fengcheng Wu +8
The emerging field of valleytronics aims to exploit the valley pseudospin of electrons residing near Bloch band extrema as an information carrier. Recent experiments demonstrating…
Neutral and Charged Inter-Valley Biexcitons in Monolayer MoSe
Kai Hao, Lixiang Xu, Judith F. Specht +10
In atomically thin transition metal dichalcogenides (TMDs), reduced dielectric screening of the Coulomb interaction leads to strongly correlated many-body states, including exciton…
Coherent and Incoherent Coupling Dynamics between Neutral and Charged Excitons in Monolayer MoSe2
Kai Hao, Lixiang Xu, Philipp Nagler +7
The optical properties of semiconducting transition metal dichalcogenides are dominated by both neutral excitons (electron-hole pairs) and charged excitons (trions) that are stable…
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…
