Abstract

Transparent Conductors (TCs) exhibit optical transparency and electron conductivity, and are essential for many opto-electronic and photo-voltaic devices. The most common TCs are electron-doped oxides, which are limited in the choice of possible dopants, as transitions metals most often are not suitable, in view of their tendency to form strong bond with oxygen. Non-oxides TCs have the potential of extending the class of materials to the magnetic realm, bypass technological bottlenecks, and bring TCs to the field of spintronics. Here we propose new functional materials that combine transparency and conductivity with magnetic spin polarization that can be used for spintronic applications, such as spin filters. By using high-throughput first-principles techniques, we identified a large number of potential TCs, including non-oxides materials. Our results indicate that proper doping with transition metals introduces a finite magnetization that can provide spin filtering up to 90% in the electrical conductivity, still maintaining a transparency greater than 90%.

透明导体（TC）具有光学透明性和电子导电性，是许多光电子和光电设备的基本材料。最常见的透明导电体是电子掺杂的氧化物，但由于过渡金属容易与氧形成强键，因此在选择掺杂剂时受到限制。非氧化物晶体管有可能将这一类材料扩展到磁性领域，绕过技术瓶颈，并将晶体管带入自旋电子学领域。通过使用高通量第一原理技术，我们发现了大量潜在的自旋电子材料，包括非氧化物材料。我们的研究结果表明，过渡金属的适当掺杂引入了有限磁化，可提供高达 90% 的自旋滤波电导率，同时仍能保持大于 90% 的透明度。

期刊介绍： Acta Materialia serves as a platform for publishing full-length, original papers and commissioned overviews that contribute to a profound understanding of the correlation between the processing, structure, and properties of inorganic materials. The journal seeks papers with high impact potential or those that significantly propel the field forward. The scope includes the atomic and molecular arrangements, chemical and electronic structures, and microstructure of materials, focusing on their mechanical or functional behavior across all length scales, including nanostructures.
