The electronic structure of Pd-Y-Si glass has been investigated by ESCA and quantum chem- ical calculation.It was found that the valence electrons of Y transferred to Si atoms in this metallic glass,forming polar covalent bonds.Perhaps these strong covalent bonds link Si and Y atoms to form clusters that hinder the process of crystallization.

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。
