DOI: 10.1021/acsphotonics.0c01159
Abstract: In the 1H monolayer transition metal dichalcogenide, the inversion symmetry is broken, while the reflection symmetry is maintained. On the other hand, in the bilayer, the inversion symmetry is rest... read more here.

DOI: 10.1063/1.5087440
Abstract: The valley of transition metal dichalcogenides provides an additional platform to manipulate spin due to its unique selection rule. Normally, intralayer optical transitions in the magnetic field show a Zeeman splitting with a g factor… read more here.
