Breakthrough in Iron-Based Superconductivity Unveiled
Researchers at the University of California, Irvine have discovered how atomic-scale mechanics enhance superconductivity in iron selenide (FeSe) films on strontium titanate (STO) substrates. Using advanced vibrational spectroscopy, they observed new phonons at the interface, which couple with electrons to increase the superconductivity transition temperature to 65 Kelvin, the highest for its class. This study, published in Nature, highlights the role of electron-phonon coupling and interface uniformity in superconductivity, paving the way for scalable superconductor applications in quantum computing and other fields.
