Pressure-Induced Superconductivity in Flat-Band Kagome Compounds Pd3P2(S1-xSex)8
文献摘要：
We performed high-pressure transport studies on the flat-band Kagome compounds,Pd3P2(S1-xSex)8(x=0,0.25),with a diamond anvil cell.For both compounds,the resistivity exhibits an insulating behavior with pressure up to 17 GPa.With pressure above 20 GPa,a metallic behavior is observed at high temperatures in Pd3P2S8,and superconductivity emerges at low temperatures.The onset temperature of superconducting transition Tc rises monotonically from 2K to 4.8 K and does not saturate with pressure up to 43 GPa.For the Se-doped compound Pd3P2(S0.75Se0.25)8,the Tc is about 1.5 K higher than that of the undoped one over the whole pressure range,and reaches 6.4 K at 43 GPa.The upper critical field with field applied along the c axis at typical pressures is about 50％of the Pauli limit,suggesting a 3D superconductivity.The Hall coefficient in the metallic phase is low and exhibits a peaked behavior at about 30 K,which suggests either a multi-band electronic structure or an electron correlation effect in the system.
