Query: A de Hass-van Alphen study of the Type-II Dirac semimetal candidates
  $A$Te$_2$ ($A =$ Pt, Pd)   We report on a magneto-transport and quantum oscillations study on high
quality single crystals of the transition metal di-tellurides PtTe$_2$ and
PdTe$_2$. The de Haas-van Alphen (dHvA) oscillations in the magnetization
measurements on PtTe$_2$ reveal a complicated, anisotropic band structure
characterized by low effective masses and high mobilities for the carriers.
Extracted transport parameters for PtTe$_2$ reveal a strong anisotropy which
could be related to the tilted nature of Dirac cone. Using a Landau level fan
diagram analysis we find at least one Fermi surface orbit with a Berry phase of
$\pi$ consistent with Dirac electrons for both PtTe$_2$ and PdTe$_2$. The light
effective mass and high mobility are also consistent with Dirac electrons in
PtTe$_2$. Our results suggest that similar to PdTe$_2$, PtTe$_2$ might also be
a three dimensional Dirac semimetal.
