Abstract
The fast temperature ramping Hg-vapor annealing (FTRA) process has bee n used for growth of superconducting Hg-based cuprate thin films on (1 00) LaAlO3 substrates. The film/substrate interface chemical reactions and the formation of a CaHgO2 impurity phase have been effectively re duced with adoption of the FTRA process. A zero-resistance superconduc ting transition temperature of 128 K and critical current densities of up to 1.4 x 10(6) A/cm(2) at 77 K and 2.5 x 10(5) A/cm(2) at 110 K an d zero field have been obtained.
