Optically Activated Superconductivity in MgB2 via Electroluminescent GaP Inhomogeneous Phase
arXiv · 2603.20719
The Takeaway
By embedding light-emitting particles into a standard superconductor, researchers found that the resulting internal light field physically pushes on the crystal lattice. This interaction strengthens the electron-pairing mechanism, allowing the material to carry electricity without resistance more effectively than normal.
From the abstract
Experimental results demonstrate a viable strategy for tuning the superconducting properties of MgB2 through the incorporation of an electroluminescent inhomogeneous phase, revealing an interfacial light-phonon-electron synergistic mechanism that enhances superconductivity in conventional phonon-mediated systems. By introducing GaP electroluminescent inhomogeneous phases into MgB2 and activating their emission in situ through the application of a bias current during measurements, it is experimen
