Abstract

The phenomenon of high-temperature superconductivity in the mercury-based cuprates HgBa2CuO4+δ and HgBa2CaCu2O6+δ is investigated. Additionally, the growth and characterization of samples is discussed. It is shown that the doping of HgBa2CuO4+δ samples can be controlled by annealing them under certain conditions to generate samples with different doping levels and superconducting transition temperatures. Finally, the effect of using different amounts of HgO during growths of HgBa2CaCu2O6+δ is discussed and it is shown that using more HgO leads to samples with higher transition temperatures but broader superconducting transitions.
