  We report a first-principles Wannier function study of the electronic
structure of PdTe. Its electronic structure is found to be a broad
three-dimensional Fermi surface with highly reduced correlations effects. In
addition, the higher filling of the Pd $d$-shell, its stronger covalency
resulting from the closer energy of the Pd-$d$ and Te-$p$ shells, and the
larger crystal field effects of the Pd ion due to its near octahedral
coordination all serve to weaken significantly electronic correlations in the
particle-hole (spin, charge, and orbital) channel. In comparison to the Fe
Chalcogenide e.g., FeSe, we highlight the essential features
(quasi-two-dimensionality, proximity to half-filling, weaker covalency, and
higher orbital degeneracy) of Fe-based high-temperature superconductors.
