superconducting diode effect

Fe(Se,Te) is a superconductor characterized by strong spin-orbit interaction and high superconducting critical parameters. In thin-film heterostructures, it exhibits the superconducting diode effect. In this study, we evaluated the superconducting diode characteristics of FeSe1-xTex/FeTe (x = 0.5, 0.6, 0.7) thin-film devices and found that both the superconducting critical current density and the rectification efficiency are maximized at x = 0.6.
