摘要: Abstract Understanding the normal state transport properties in hole-doped high-temperature cuprate superconductors (HTCSs) is a challenging task which has been widely believed to be one of key steps toward revealing pairing mechanism superconductivity. Here, we present true intrinsic and universal doping dependence in-plane dc conductivity for all underdoped HTCSs. The normalized that at optimal can represented by simple exponential formula. behavior square nodal Fermi velocity derived high-resolution laser-based angle-resolved photoemission spectroscopy superconducting follows reasonably well behavior. Our findings suggest commonality low-energy quasiparticles both states place stringent constraint on superconductivity
