Advances in the Physics of High-Temperature Superconductivity
Figure 1 (A) Crystal structure of La 2 CuO 4, the "parent compound" of the La (2– x) Sr x CuO 4 family of high-temperature superconductors. The crucial structural subunit is the Cu-O 2 plane, which extends in thea-b direction; parts of three CuO 2 planes are shown. Electronic couplings in the interplane (c) direction are very weak the La 2 CuO 4 family …

What If You Did Have A Room Temperature Superconductor?
DOE Explains.. perconductivity | Department of Energy
Five Nobel Prizes in Physics have been awarded for research in superconductivity (1913, 1972, 1973, 1987, and 2003). Approximately half of the elements in the periodic table display low temperature superconductivity, but applications of superconductivity often employ easier to use or less expensive alloys.
High-Temperature Superconductivity Understood at Last
Where electrons struggled to hop, superconductivity was weak. Where hopping was easy, superconductivity was strong. The relationship between hopping energy and Cooper pair density closely matched a sophisticated numerical prediction from 2021 by Tremblay and colleagues, which argued that this relationship should follow from …

Superconductivity was discovered in 1911 by Kamerlingh Onnes and Holst in mercury at the temperature of liquid helium (4.2 K). It took almost 50 years until in 1957 a microscopic theory of superconductivity, the so-called BCS theory, was developed. Since the discovery a number of superconducting materials were found with transition temperatures up to 23 …
Low-temperature superconductors: Nb3Sn, Nb3Al, and NbTi
1. Introduction. Low-temperature superconductors are typically defined as materials with critical temperature (T c) values lower than approximately 20 K, which is the storage temperature of liquid H 2.Nb-based superconductors, such as Nb 3 Sn and NbTi, and superconducting solders, including PbBi, are representative low-temperature …
