Query: Andreev reflection and subgap conductance in monolayer $MoS_2$
  ferromagnet/$s$ and $d$-wave superconductor junction   The accurate and proper form of electron-hole excitations and corresponding
Dirac-like spinors of monolayer molybdenum disulfide superconductor are exactly
obtained. Andreev reflection and resulting subgap conductance in a
$MoS_2$-based ferromagnetic superconducting (F/S) junction is accurately
investigated in terms of dynamical characteristics of system. Due to
spin-splitting energy gap in the valence band and nondegenerate $K$ and $K'$
valleys, the ferromagnetic exchange energy $\sigma h$ can cause a distinct
behavior of Andreev process between spin-up and spin-down charge carriers
belonging to different valleys. The chemical potential is necessarily fixed by
a determined range in order to occur the retro Andreev reflection. Given
one-particle superconducting bispinors enable us to explicitly involve the
anisotropic superconducting gap $\Delta_S$ under electron-hole conversion,
i.e., taking place in $d$-wave pair coupling. The effect of such gap is exactly
explained in terms of the dependence of the Andreev process on the electron
incidence angle at the interface.
