High-throughput and combinatorial materials science methods were used to investigate the dependence of the work function in the Ni-Si system on the B content (0-30 at. %). Alloying of NiSi is used to adapt its properties to suit the needs as a gate electrode material. Thin-film materials libraries were fabricated and investigated with respect to their structural and electrical properties. Further the work function values of selected samples in the region of interest were analyzed. The results show that the work function can be adjusted between 4.86 eV (B = 4.2 at. %) and 5.16 eV (B = 29.2 at. %) for (NiSi)B .
采用高通量和组合材料科学方法研究了 Ni-Si 体系功函数对 B 含量(0-30 原子%)的依赖关系。合金化 NiSi 用于调整其性能以满足作为栅电极材料的需求。制备了薄膜材料库,并研究了它们的结构和电学性能。进一步分析了感兴趣区域中选定样品的功函数值。结果表明,(NiSi)B 的功函数可以在 4.86 eV(B = 4.2 原子%)和 5.16 eV(B = 29.2 原子%)之间进行调整。
