What Does STJ Stand For?

STJ stands for Superconducting Tunnel Junction

STJ, or Superconducting Tunnel Junction, is a quantum device that consists of two superconductors separated by a thin insulating barrier. This configuration allows for the tunneling of Cooper pairs—pairs of electrons that move through the superconductor without resistance—across the junction. STJs exhibit unique electrical and thermal properties, making them valuable in various applications such as cryogenic detectors, quantum computing, and high-precision measurements in condensed matter physics. Their ability to operate at very low temperatures enhances their performance in detecting low-energy photons and other subatomic particles.
