非晶态Pd-Y-Si合金的电子结构
ELECTRONIC STRUCTURE OF AMORPHOUS Pd-Y-Si ALLOY
【摘要】 用光电子能谱及量子化学计算研究了Pd-Y-Si非晶态合金的电子结构。结果表明:在该体系中,Y向Si迁移电子并形成极性共价键,Y-Si极性共价键可能阻碍结晶时原子重排。
【Abstract】 The electronic structure of Pd-Y-Si glass has been investigated by ESCA andquantum chemical calculation. It was found that the valence electrons of Y transferred to Siatoms in this metallic glass, forming polar covalent bonds. Perhaps these strong covalentbonds Link Si and Y atoms to form clusters that hinder the process of crystallization.
