The Quest for High-Temperature Superconductors: Fiction or Future?

| Condensed Matter |

Definition of High-Temperature Superconductors High-temperature superconductors (HTS) are materials that exhibit superconductivity-zero electrical resistance and the expulsion of magnetic fields-at temperatures significantly higher than traditional superconductors. Unlike conventional superconductors that require cooling near absolute zero, HTS operate at comparatively elevated temperatures, often above the boiling point of liquid nitrogen (77 K), making them more practical […]
