(Nanowerk Spotlight) Charge density wave (CDW) is a quantum mechanical phenomenon, which induces distortion in the crystal structures of some low-dimensional (1D or 2D) metals, when the temperature is ...

Atoms of a tantalum disulfide (TaS2) crystal with a 2D endotaxial layer in the center. The pink cloud represents the charge density wave, a clumped pattern of electrons, surrounding the 2D layer.

According to the team, the part is the first useful device that exploits the potential of charge density waves to modulate an electrical current through a 2D material. Apart from having the potential ...
