In this study,Kagome superconductors,i.e.,CsV_(3)Sb_(5)single crystals and its Ta-doped variant,Cs(V_(0.86)Ta_(0.14))_(3)Sb_(5),were studied in detail via specific heat measurements.Results revealed that the charge de...
V-based kagome superconductors AV_(3)Sb_(5)(A=K,Rb,and Cs)host a charge density wave(CDW)and a topological nontrivial band structure,thereby providing a great platform to study the interplay of superconductivity(SC),C...
