The most promising approach for improving the electrical performance of connectors used in semiconductor test sockets involves increasing their electrical conductivity by incorporating one-dimensional (1D) conductive materials between zero-dimensional (0D) conductive materials. In this study, FeCo nanowires were synthesized by electroplating to prepare a material in which 1D materials could be magnetically aligned. Moreover, the nanowires were coated with highly conductive Au. The magnetization per unit mass of the synthesized FeCo and FeCo@Au nanowires was 167.2 and 13.9 emu/g, respectively. The electrical performance of rubber-based semiconductor connectors before and after the introduction of synthetic nanowires was compared, and it was found that the resistance decreased by 14%. The findings reported herein can be exploited to improve the conductivity of rubber-type semiconductor connectors, thereby facilitating the development of connectors using 0D and 1D materials.
提高半导体测试插座中使用的连接器电气性能最有前景的方法是，通过在零维（0D）导电材料之间加入一维（1D）导电材料来提高其电导率。在本研究中，通过电镀合成了FeCo纳米线，以制备一种能使一维材料磁取向的材料。此外，纳米线还用高导电性的Au进行了包覆。合成的FeCo和FeCo@Au纳米线的单位质量磁化强度分别为167.2和13.9 emu/g。比较了引入合成纳米线前后橡胶基半导体连接器的电气性能，发现电阻降低了14%。本文报道的研究结果可用于提高橡胶型半导体连接器的导电性，从而推动使用0D和1D材料的连接器的发展。
