The Laser-induced Thermionic Vacuum Arc method was applied to optimize magnesium-silver (Mg:Ag) alloys, which can be potentially used as stable metallic cathodes for optoelectronic devices. Besides lowering the cathode work function given by the magnesium that improves the electron injection, Mg:Ag alloys induce a higher electrical conductivity, estimated here to be 3.42 × 10⁷ S m^–1 for AgMg₃, compared with 2.64 × 10⁷ S m⁻¹, estimated here for Mg thin films. Mg:Ag alloys avoid the critical issue of Mg oxidation for better charge injection in optoelectronic active layers. By improving the Thermionic Vacuum Arc technique with the laser beam, this method enables the control of the silver concentration in these alloys due to photonic processes. The uniformity of metallic thin films, compactness, and high purity are the primary advantages of the Laser-induced Thermionic Vacuum Arc method.

应用激光诱导的热电子真空电弧法优化镁银（Mg：Ag）合金，可以将其用作光电器件的稳定金属阴极。Mg：Ag合金除了降低镁能改善电子注入的阴极功函数外，还诱导出更高的电导率，与2.64×10 ⁷ S m相比，此处的AgMg ₃估计为3.42×10 ⁷ S m ^–1。^-1，这里估算的是镁薄膜。Mg：Ag合金避免了Mg氧化的关键问题，从而可以在光电有源层中更好地注入电荷。通过使用激光束改进热电子真空电弧技术，该方法可以控制由于光子过程而导致的这些合金中银的浓度。金属薄膜的均匀性，致密性和高纯度是激光诱导的热电子真空电弧法的主要优点。
