Technique Elucidates Role of Phonons in Copper-Based Superconductivity
Since the 1980s, scientists have been well aware of high-temperature superconducting copper-based materials, or cuprates. Below a specific temperature (roughly -130°C), electrical resistance disappears from these materials and magnetic flux fields are released. However, the reason for that superconductivity continues to be discussed and investigated.
