摘要： Under one aspect, a method of making a superconductor wire includes providing an oxide superconductor layer overlaying a substrate; forming a substantially continuous barrier layer over the oxide superconductor layer, the barrier layer including metal; depositing a layer of metal particles over the barrier layer, said depositing including applying a liquid including metal particles over the barrier layer; and sintering the layer of metal particles to form a substantially continuous metal layer over the barrier layer. In one or more embodiments, the oxide superconductor layer is oxygen-deficient, and the method may include oxidizing the oxygen-deficient oxide superconductor layer. At least a portion of the sintering and the oxidizing may occur simultaneously, for example by performing them at an oxygen partial pressure and a temperature sufficient to both sinter the metal particles and to oxidize the oxygen-deficient oxide superconductor layer.
