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.

Information and noise in quantum measurement [PDF]

, 1999
Even though measurement results obtained in the real world are generally both noisy and continuous, quantum measurement theory tends to emphasize the ideal limit of perfect precision and quantized measurement results.
