Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk ...

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 ...

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 ...

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 ...

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 ...

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 ...
