The in-plane stability of these 2D crystals is provided by strong covalent bonds, but the atomically thin layers are attached to each other through weak van der Waals interactions, similar to how a ...

This next generation of 2D-2D heterostructures goes beyond van der Waals thanks to the strong covalent bonds between its 2D materials. Combining the best of different crystals to obtain the ...

Researchers have synthesized bulk van der Waals (vdW) materials at near-room ... weak vdW forces instead of strong covalent or metallic bonds. The study is published in Nature Materials.
