Abstract

We report coexistence of bulk superconductivity and charge density wave (CDW) with superconducting critical temperature Tc = 3.8 K in Cu intercalated quasi-two-dimensional crystals of ZrTe3. The Cu intercalation results in the expansion of the unit cell orthogonal to the Zr-Zr metal chains (b - axis) and partial filling of CDW energy bandgap without obvious shift of CDW transition temperature. b - axis resistivity ?Rhob is not related to CDW, and its dominant scattering mechanism for both ZrTe3 and Cu0.05ZrTe3 is the electron - electron Umklapp scattering.
