Tuning moiré excitons and correlated electronic states through layer degree of freedom - Nature.com

Twisted heterostructures of transition metal dichalcogenides host the so-called moiré excitons, or intralayer excitons modified by the moiré potential. Here the authors show tunability of the moiré excitons and the coexisting correlated electronic states in W…

The back-gated angle-aligned WSe2/WS2 heterojunction device is schematically shown in Fig. 1a, which includes three different regions in the same device: 1L/1L WSe2/WS2, 2L/1L WSe2/WS2, and 3L/1L WSe… [+18159 chars]
