Porous materials are widely used for gas storage, separation, catalysis, and environmental purification. Their functionality arises from nanoscale pores that allow molecules to be selectively captured ...

Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ferroelectric thin films. The work opens the door to new techniques for ...

Van der Waals heterostructures are artificial materials formed by stacking atomically thin layers of distinct two-dimensional crystals through weak interlayer forces. This modular approach transcends ...

In general, when you measure material properties such as optical permittivity, your measurement doesn’t depend on the direction in which you make it. However, recent research has shown that this is ...

Certain two-dimensional (2D) van der Waals-bonded bilayers (e.g., WTe₂ and h-BN) exhibit “sliding ferroelectricity (SF),” where electric polarization arises from specific stacking configurations ...

Researchers have shown it is possible to expand the field of twistronics—literally. They have demonstrated a technique that ...

Van der Waals epitaxy is an approach to crystalline growth that exploits weak, non-covalent interactions between layers to bypass the constraints of lattice mismatch. By depositing two-dimensional (2D ...

(Nanowerk Spotlight) Advances in semiconductor technology have reached a critical turning point. Silicon-based transistor technology, central to electronics, faces increasing limitations due to the ...

Researchers from the Institute for Integrated Cell-Material Sciences, Kyoto University, have developed the first three-dimensional van der Waals open frameworks. This discovery challenges the common ...

Van der Waals forces can tune ferroelectric thin films, improving control over material properties for smaller, more energy-efficient electronics. “Epitaxy is when you deposit a crystalline layer of ...
