The layered metal Ti2PTe2
Abstract
<p>Crystals of Ti<sub>2</sub>PTe<sub>2</sub> have been synthesised by chemical vapour transport. Ti<sub>2</sub>PTe<sub>2</sub> crystallises, isostructural to the mineral tetradymite (Bi<sub>2</sub>STe<sub>2</sub>), in the space group R3̄m with unit-cell parameters a = 3.6387(2) Å and c = 28.486(2) Å for the hexagonal setting. In the structure, layers of isolated phosphide and telluride anions form an ordered close sphere-packing with titanium cations filling two-thirds of the octahedral voids. From XANES fluorescence, the presence of Ti<sup>4+</sup> is clearly established. In accordance with the ionic formula (Ti<sup>4+</sup>)<sub>2</sub>(P <sup>3-</sup>)(Te<sup>2-</sup>)<sub>2</sub>(e<sup>-</sup>) metallic conductivity (ρ = 40 μΩ cm at 300 K) and nearly temperature-independent paramagnetism are found. The electronic band structure shows bands of titanium states crossing the Fermi level in directions corresponding to the ab-plane and a band gap along the c-axis.</p>
