Measurement of the optical dielectric function of transition metal dichalcogenide monolayers: MoS2, MoSe2, WS2 and WSe2
Yilei Li, Alexey Chernikov, Xian Zhang +7
We report a determination of the complex in-plane dielectric function of monolayers of four transition metal dichalcogenides: MoS2, MoSe2, WS2 and WSe2, for photon energies from 1.…
Measurement of lateral and interfacial thermal conductivity of single- and bi-layer MoS2 and MoSe2 using refined optothermal Raman technique
Xian Zhang, Dezheng Sun, Yilei Li +6
Atomically thin materials such as graphene and semiconducting transition metal dichalcogenides (TMDCs) have attracted extensive interest in recent years, motivating investigation i…
Exciton Binding Energy and Nonhydrogenic Rydberg Series in Monolayer WS2
Alexey Chernikov, Timothy C. Berkelbach, Heather M. Hill +6
We have experimentally determined the energies of the ground and first four excited excitonic states of the fundamental optical transition in monolayer WS2, a model system for the…
