Definition: Van der Waals materials encompass a broad category of layered substances, including individual van der Waals materials and their engineered stacks known as van der Waals heterostructures, ...

Van der Waals heterostructures are engineered by stacking different van der Waals materials in a controlled sequence, allowing the creation of new materials with tailored properties. This technique ...

Different stacks in 2D van der Waals materials affected by this phenomenon, dubbed "sliding ferroelectricity," are related by a large, device-scale shift of two layers by several angstroms. Past ...

For the development of van der Waals thin films with high electronic performance, mechanical stretchability, and permeability for highly flexible, adaptable and breathable bioelectronic membranes. The ...

Computer Chips Today, according to New Scientist, computer chips are made of silicon. Silicon is readily available and capable of containing a large number of transistors within a tiny surface area.

With their spontaneous electrical polarisations switchable by an external electric field, ferroelectrics have wide-ranging applications in ...

It has long been known that at microscopic size scales, the so-called van der Waals forces—the attractive and repulsive forces between two dipole molecules—become significant. Essentially ...
