  Density functional theory (DFT) based ab-initio calculations of electronic,
phononic, and superconducting properties of 1T MoS2 are reported. The phonon
dispersions are computed within density-functional-perturbation-theory (DFPT).
We have also computed Eliashberg function alpha2Fomega and electron-phonon
coupling constant lambda from the same. The superconducting transition
temperature (Tc) computed within the McMillan-Allen-Dynes formula is found in
good agreement with the recent experimental report. We have also evaluated the
effect of pressure on the superconducting behavior of this system. Our results
show that 1T MoS2 exhibits electron-phonon mediated superconductivity and the
superconducting transition temperature rises slightly with pressure and then
decreases with further increase in pressure.
