Abstract

HgBa2Cu1-xZnxO4+δ (Hg-1201, x = 0 and 0.03) superconductors were synthesized over a wide doping range, and Zn-substitution effects on superconductivity and the pseudogap were investigated. Tc significantly decreased with Zn substitution, especially for highly underdoped samples, without changing the hole concentration. Analysis of resistivity and thermoelectric power indicated that the pseudogap temperature does not change over a wide doping range, consistent with results from Zn-substituted YBa2Cu3O6+δ.
