摘要：

The superconductors, HgBa2CanCun+1O4+2n+delta, with n = 1,2 and 3 were prepared and annealed under a variety of conditions including high-pressure oxygen. Superconducting transition temperatures T(c) are determined as a function of oxygen annealing pressure. These results show that the n = 1 and 2 materials will overdope when annealed at pressures in excess of 1 bar while n = 3 requires tens of bars.
