It is the electron doping of the BiS 2 planes that makes the material metallic and induces superconductivity. One of the most interesting characteristics of these materials is the dependence of their superconducting properties on variations in the local crystal structure and stress.
Present-day volume prices of HTSs range from $150 to $200/kA-m. Many analyses of the commercial viability of superconducting applications show that a conductor cost of $50/kA-m is the tipping point for widespread application for electric power use. A long-range outlook projects HTS costs below $10/kA-m when produced on a very large scale (14).
Since the unexpected report in 1987 of high-temperature superconductivity at 93 K (1), the idea that HTSs could revolutionize the electric power industry (3), going far beyond the classical application of superconductivity to electromagnets, has been pursued.
Historically, the high-energy physics community has provided the dominant demand for new superconductors, and indeed it is now driving the demand for both LTSs and HTSs as essential components of ultra-high energy particle colliders.
