Experimental Observation of Strong Coupling Between an Epsilon-Near-Zero Mode in a Deep Subwavelength Nanofilm and a Gap Plasmon Mode

Autor: Hendrickson, Joshua R., Vangala, Shivashankar, Dass, Chandriker K., Gibson, Ricky, Leedy, Kevin, Walker, Dennis, Cleary, Justin W., Luk, Ting S., Guo, Junpeng

Strong coupling is a phenomenon which occurs when the interaction between two resonance systems is so strong that the oscillatory energy exchange between them exceeds all dissipative loss channels. Each resonance can then no longer be described indiv

Neutral and Charged Inter-Valley Biexcitons in Monolayer MoSe$_2$

Autor: Hao, Kai, Xu, Lixiang, Specht, Judith F., Nagler, Philipp, Tran, Kha, Singh, Akshay, Dass, Chandriker Kavir, Schüller, Christian, Korn, Tobias, Richter, Marten, Knorr, Andreas, Li, Xiaoqin, Moody, Galan

Publikováno v: Nature Communications 8, 15552 (2017)

In atomically thin transition metal dichalcogenides (TMDs), reduced dielectric screening of the Coulomb interaction leads to strongly correlated many-body states, including excitons and trions, that dominate the optical properties. Higher-order state

Coherent and Incoherent Coupling Dynamics between Neutral and Charged Excitons in Monolayer MoSe2

Autor: Hao, Kai, Xu, Lixiang, Nagler, Philipp, Singh, Akshay, Tran, Kha, Dass, Chandriker Kavir, Schüller, Christian, Korn, Tobias, Li, Xiaoqin, Moody, Galan

The optical properties of semiconducting transition metal dichalcogenides are dominated by both neutral excitons (electron-hole pairs) and charged excitons (trions) that are stable even at room temperature. While trions directly influence charge tran

Direct Measurement of Exciton Valley Coherence in Monolayer WSe$_2$

Autor: Hao, Kai, Moody, Galan, Wu, Fengcheng, Dass, Chandriker Kavir, Xu, Lixiang, Chen, Chang-Hsaio, Li, Ming-Yang, Li, Lain-Jong, MacDonald, Allan H., Li, Xiaoqin

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 as a useful information carrier analogous to electronic charge or spi

Intrinsic Exciton Linewidth in Monolayer Transition Metal Dichalcogenides

Autor: Moody, Galan, Dass, Chandriker Kavir, Hao, Kai, Chen, Chang-Hsiao, Li, Lain-Jong, Singh, Akshay, Tran, Kha, Clark, Genevieve, Xu, Xiaodong, Bergauser, Gunnar, Malic, Ermin, Knorr, Andreas, Li, Xiaoqin

Publikováno v: Nature Communications 6, 8315 (2015)

Monolayer transition metal dichalcogenides feature Coulomb-bound electron-hole pairs (excitons) with exceptionally large binding energy and coupled spin and valley degrees of freedom. These unique attributes have been leveraged for electrical and opt
