Highly tunable layered exciton in bilayer WS${}_2$: linear quantum confined Stark effect versus electrostatic doping

Sarthak Das, Medha Dandu, Garima Gupta +6

In 1H monolayer transition metal dichalcogenide, the inversion symmetry is broken, while the reflection symmetry is maintained. On the contrary, in the bilayer, the inversion symme…
