Superconductivity at 2.3 K in the Misfit Compound (PbSe)₁.₁₆(TiSe₂)₂
Abstract
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.
