Fermiology and evidence of conventional superconductivity in the type-II Dirac semimetal PdTe₂

We use electrical transport and heat capacity measurements on high-quality single crystals of the recently discovered superconducting type-II Dirac semimetal PdTe₂, to probe the nature of its superconducting phase. The magnitude of the electronic heat-capacity anomaly at Tc, the low temperature exponential T dependence of the heat capacity, the linear H dependence of the T = 0 electronic Somerfield coefficient, and a conventional H − T phase diagram establish that the superconductivity in PdTe₂ is conventional in nature despite the presence of a topologically nontrivial Fermi surface band, which contributes to the electrical conduction. The Fermi surface of PdTe₂ is investigated by the dHvA oscillations.
