Disorder of Excitons and Trions in Monolayer MoSe2
Jue Wang, Christina Manolatou, Yusong Bai +3
The optical spectra of transition metal dichalcogenide (TMDC) monolayers are dominated by excitons and trions. Here we establish the dependences of these optical transitions on dis…
The Structure and Dispersion of Exciton-Trion-Polaritons in Two-Dimensional Materials: Experiments and Theory
Okan Koksal, Minwoo Jung, Christina Manolatou +3
The nature of trions and their interaction with light has remained a puzzle. The composition and dispersion of polaritons involving trions provide insights into this puzzle. Trions…
Exciton-Trion-Polaritons in Two-Dimensional Materials
Farhan Rana, Okan Koksal, Minwoo Jung +3
We present a many-body theory for exciton-trion-polaritons in doped two-dimensional materials. Exciton-trion-polaritons are robust coherent hybrid excitations involving excitons, t…
Many-body theory of radiative lifetimes of exciton-trion superposition states in doped two-dimensional materials
Farhan Rana, Okan Koksal, Minwoo Jung +2
Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged exciton…
A Many-Body Theory of the Optical Conductivity of Excitons and Trions in Two-Dimensional Materials
Farhan Rana, Okan Koksal, Christina Manolatou
The optical spectra of two dimensional (2D) materials exhibit sharp absorption peaks that are commonly identified with exciton and trions (or charged excitons). In this paper, we s…
Radiative and Non-Radiative Exciton Energy Transfer in Monolayers of Two-Dimensional Transition Metal Dichalcogenides
Christina Manolatou, Haining Wang, Weimin Chan +2
We present results on the rates of interlayer energy transfer between excitons in two-dimensional transition metal dichalcogenides (TMDs). We consider both radiative (mediated by r…
Fast Exciton Annihilation by Capture of Electrons or Holes by Defects via Auger Scattering in Monolayer Metal Dichalcogenides
Haining Wang, Jared H. Strait, Changjian Zhang +4
The strong Coulomb interactions and the small exciton radii in two-dimensional metal dichalcogenides can result in very fast capture of electrons and holes of excitons by mid-gap d…
Radiative Lifetimes of Excitons and Trions in Monolayers of Metal Dichalcogenide MoS2
Haining Wang, Changjian Zhang, Weimin Chan +3
We present results on the radiative lifetimes of excitons and trions in a monolayer of metal dichalcogenide MoS2. The small exciton radius and the large exciton optical oscillator…

Parinita Nene, Jared H. Strait, Wei-Min Chan +5
A variety of different graphene plasmonic structures and devices have been proposed and demonstrated experimentally. Plasmon modes in graphene microstructures interact strongly via…
Absorption of Light by Excitons and Trions in Monolayers of Metal Dichalcogenide MoS: Experiments and Theory
Changjian Zhang, Haining Wang, Weimin Chan +2
We measure the optical absorption spectra and optical conductivities of excitons and trions in monolayers of metal dichalcogenide MoS and compare the results with theoretical…
Confined Plasmons in Graphene Microstructures: Experiments and Theory
Jared H. Strait, Parinita S. Nene, Wei-Min Chan +5
Graphene, a two-dimensional material with a high mobility and a tunable conductivity, is uniquely suited for plasmonics. The frequency dispersion of plasmons in bulk graphene has b…
