The 1T polytype of TaS 2 undergoes the transition from a normal metallic phase to an incommensurate CDW (IC-CDW) phase at 545 K, to a nearly commensurate CDW (NC-CDW) phase at 350 K and, finally, to a ...

Researchers from Chalmers University of Technology and Politecnico di Milano have identified a crucial new aspect of charge density modulations in cuprate high critical temperature superconductors.
