Abstract

The microchemical composition and the electronic structure of the two superconductors HgBa₂Ca₂Cu₃O _8+δ (Hg-1223) and HgBa₂Ca₁Cu ₂O_6+δ (Hg-1212) were analyzed with the technique of photoemission with high spatial resolution. This enabled primary spectral peaks to be separated from their satellites due to local charging induced by the primary photon beam. Each sample contains superconducting and impurity phases with inhomogeneous spatial distributions. The oxygenation-induced increase in the critical temperature is related to a increase in the Cu-O plane carrier concentration.
