Superconductivity at 2.3 K in the misfit compound (PbSe)1.16(TiSe2)2
نویسندگان
چکیده
The structural misfit compound PbSe 1.16 TiSe2 2 is reported. It is a superconductor with a Tc of 2.3 K. PbSe 1.16 TiSe2 2 derives from a parent compound, TiSe2, which shows a charge-density wave transition and no superconductivity. The crystal structure, characterized by high-resolution electron microscopy and powder x-ray diffraction, consists of two layers of 1T-TiSe2 alternating with a double layer of 100 PbSe. Transport measurements suggest that the superconductivity is induced by charge transfer from the PbSe layers to the TiSe2 layers.

Role of Incommensuration in the charge density wave and superconducting states of 1T-TiSe2
A brief review of some of the most recent experiments on the charge density wave (CDW) transition in 1T-TiSe2 is presented. With increasing pressure or intercalation, the CDW can be suppressed and a superconducting (SC) phase emerges. In the pristine 1T-TiSe2, a commensurate CDW develops around 202 K. These experiments show that by tuning these external parameters like pressure, or doping, the ...
متن کاملPressure induced superconductivity in pristine 1T-TiSe2.
The interplay between superconductivity and the charge-density wave (CDW) state in pure 1T-TiSe(2) is examined through a high-pressure study extending up to pressures of 10 GPa between sub-Kelvin and room temperatures. At a critical pressure of 2 GPa a superconducting phase sets in and persists up to pressures of 4 GPa. The maximum superconducting transition temperature is 1.8 K. These findings...
متن کاملHidden Order and Dimensional Crossover of the Charge Density Waves in TiSe2
Charge density wave (CDW) formation, a key physics issue for materials, arises from interactions among electrons and phonons that can also lead to superconductivity and other competing or entangled phases. The prototypical system TiSe2, with a particularly simple (2 × 2 × 2) transition and no Kohn anomalies caused by electron-phonon coupling, is a fascinating but unsolved case after decades of ...

متن کاملSuperconductivity in LaFeAs1−xPxO: effect of chemical pressures and bond covalency
We report the realization of superconductivity by an isovalent doping with phosphorus in LaFeAsO. X-ray diffraction shows that, with the partial substitution of P for As, the Fe2As2 layers are squeezed while the La2O2 layers are stretched along the c-axis. Electrical resistance and magnetization measurements show emergence of bulk superconductivity at ∼10 K for the optimally-doped LaFeAs1−xPxO ...
