Tuning band alignment and optical properties of 2D van der Waals heterostructure via ferroelectric polarization switching [PDF]

, 2020
Favourable band alignment and excellent visible light response are vital for photochemical water splitting. In this work, we have theoretically investigated how ferroelectric polarization and its reversibility in direction can be utilized to modulate the

Singular sublimation of ice and snow crystals

Nature Communications, 2018
Ice sublimation is a common, yet little-studied, heat and mass transfer problem with climatic and industrial implications. Here, the authors show that the sublimation of ice crystals is purely diffusive and is unaffected by the underlying crystalline ...

Low carrier concentration crystals of the topological insulator Bi2−xSbxTe3−ySey: a magnetotransport study

New Journal of Physics, 2014
In 3D topological insulators achieving a genuine bulk-insulating state is an important research topic. Recently, the material system (Bi,Sb) _2 (Te,Se) _3 (BSTS) has been proposed as a topological insulator with high resistivity and a low carrier ...

Terahertz emission from giant optical rectification in a van der Waals material [PDF]

Nature Materials
The exfoliation and stacking of two-dimensional van der Waals crystals have created unprecedented opportunities in the discovery of quantum phases. A major obstacle to the advancement of this field is the limited spectroscopic access due to a mismatch in

Dynamical criticality of spin-shear coupling in van der Waals antiferromagnets

Nature Communications, 2022
Van der Waals materials are characterized by two dimensional layers weakly held together by interlayer van der Waals forces. Here, the authors study how shear motions between these layers influence the magnetic properties of the van der Waals ...
