Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ...

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 ...

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 ...

Two-dimensional (2D) materials are crystalline sheets one or a few atoms thick, characterised by strong in-plane covalent bonds and weak out-of-plane van der Waals forces. Beginning with graphene, the ...
