Abstract
A superconducting article comprises a substrate, a buffer layer overlying the substrate, and a high-temperature superconducting (HTS) layer overlying the buffer layer. The HTS layer includes a plurality of nanorods. A method of forming a superconducting article comprises providing a substrate, depositing a buffer layer overlying the substrate; forming a nanodot array overlying the buffer layer; depositing an array of nanorods nucleated on the nanodot array; and depositing a high-temperature superconducting (HTS) layer around the array of nanorods and overlying the buffer layer.
Claims22
