Query: Emergent superconductivity in van der Waals Kagome material Pd3P2S8
  under high pressure   Kagome lattice systems have been proposed to host rich physics, which provide
an excellent platform to explore unusual quantum states. Here, we report on the
discovery of superconductivity in van der Waals material Pd3P2S8 under
pressure. The superconductivity is observed in Pd3P2S8 for those pressures
where the temperature dependence of the resistivity changes from a
semiconducting-like behavior to that of a normal metal. The superconducting
transition temperature Tc increases with applied pressure and reaches ~ 6.83 K
at 79.5 GPa. Combining high-pressure XRD, Raman spectroscopy and theoretical
calculations, our results demonstrate that the observed superconductivity
induced by high pressure in Pd3P2S8 is closely related to the formation of
amorphous phase, which results from the structural instability due to the
enhanced coupling between interlayer Pd and S atoms upon compression.
