ABSTRACT:
A two-step process for the preparation of a thallium-containing superconductive film is described.
In the first step of this process, an aerosol mist containing reactants necessary to produce a calcium/barium/strontium/copper precursor material is provided. This mist is subjected to radio-frequency radiation while in the plasma region, and it thereafter is deposited onto an electrically grounded substrate.
In the second step of the process, the coated substrate is contacted with thallium-containing vapor.
