0D van der Waals interfacial ferroelectricity

Nature Communications, 2023
The dimensional limit of ferroelectricity has been long explored. The critical contravention is that the downscaling of ferroelectricity leads to a loss of polarization.

Twist Angle-Dependent Interlayer Exciton in MoS₂ Bilayers Revealed by Room-Temperature Reflectance

Crystals, 2022
In 2H stacking bilayer MoS2, the exciton with an interlayer nature has been evidenced due to the hybridization of hole states among both layers. The transition energy of this interlayer exciton is located between the A and B excitons.
