Abstract

Improving the critical temperature (TC), critical magnetic field (HC), and critical current (JC) of superconducting materials has always been one of the most significant challenges in the field of superconductivity, but progress has been slow over the years. Based on the concept of injecting energy to enhance electron pairing states, in this study, we introduce green-light GaN p-n junction particles (center wavelength 550 nm) as inhomogeneous phases into MgB2 superconducting materials, forming a smart meta-superconductors structure. Leveraging the electroluminescent properties of p-n junctions, we excite and reinforce Cooper pairs, enhancing the superconducting properties of the MgB2 material. Experimental results demonstrate that compared to pure MgB2 samples, the critical transition temperature (TC) has increased by 1.2 K, the critical current (JC) has increased by 52.8%, and the Meissner effect (HC) shows significant improvement in its diamagnetic properties. This phenomenon of enhanced superconducting performance can be explained by the coupling between superconducting electrons and evanescent waves.
