(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.
Researchers at the National University of Singapore (NUS) have observed a doping-tunable charge density wave (CDW) in a single-layer semiconductor, Chromium(III) selenide (Cr 2 Se 3), extending the ...
