We present a detailed quantum oscillatory study on the Dirac type-II semimetallic candidates PdTe2 and PtTe2 via the temperature and the angular dependence of the de Haas-van Alphen (dHvA) and Shubnikov-de Haas (SdH) effects. In high quality single crystals of both compounds, i.e. displaying carrier mobilities between 10 3 and 10 4 cm 2 /Vs, we observed a large non-saturating magnetoresistivity (MR) which in PtTe 2 at a temperature T = 1. 3 K, leads to an increase in the resistivity up to 5… Expand

Thermal transport by electrons and phonons in PdTe2: an ab initio study.
This work studies the lattice and electronic thermal conductivity of PdTe2 using mode-level ab initio calculations and finds its thermalonductivity is ∼35 W m-1 K-1 on the a-axis at room temperature, mainly attributed to the strong lattice anharmonicity and electron-phonon interactions. Expand
Electronic and topological properties of group-10 transition metal dichalcogenides.

Enhanced, homogeneously type-II superconductivity in Cu-intercalated PdTe$_2$.
As the critical temperature of the superconducting phase goes up from 1.7 K to 2.4 K on Cu-intercalation, the mixed phase disappears and the system comes homogeneously type-II, which may be attributed to an averaging effect caused by quasiparticle exchange between type-I and type- II domains mediated by the Cu atoms.
