Superconducting and structural properties of the type-I superconductor PdTe2 under high pressure
Abstract
<p>The transition metal dichalcogenide PdTe<sub>2</sub> has attractive features based on its classification as a type-II Dirac semimetal and the occurrence of type-I superconductivity, providing a platform for discussion of a topological superconductor. Our recent work revealed that type-I superconductivity persists up to pressures of ∼2.5 GPa and the superconducting transition temperature <i>T</i><sub>c</sub> reaches a maximum at around 1 GPa, which is inconsistent with the theoretical prediction. To understand its nonmonotonic variation and investigate superconductivity at higher pressures, we performed structural analysis by x-ray diffraction at room temperature below 8 GPa and electrical resistivity measurements at low temperatures from 1 to 8 GPa. With regard to the superconductivity beyond 1 GPa, the monotonic decrease in <i>T</i><sub>c</sub> is reproduced without any noticeable anomalies; <i>T</i><sub>c</sub> changes from 1.8 K at 1 GPa to 0.82 K at 5.5 GPa with <i>dT</i><sub>c</sub>/<i>dP</i>∼-0.22 K/GPa. The crystal structure with space group <i>P</i>3¯<i>m</i>1 is stable in the pressure range we examined. On the other hand, the normalized pressure-strain analysis (finite strain analysis) indicates that the compressibility changes around 1 GPa, suggesting that a Lifshitz transition occurs. We here discuss the effect of pressure on the superconducting and structural properties based on the comparison of these experimental results.</p>
