Abstract

Results are presented from analyzing different ways of obtaining pure atomic surfaces of In, Sn, Bi, and binary alloys In–Bi and Sn–Bi in the liquid state. The high sensitivity of characteristic electron energy loss spectroscopy to surface-active impurities is noted. The example of an In–Bi melt (6.16 at % Bi) shows the effect oxygen has on the segregation of components into surface layers. Results are presented from simultaneously measuring surface tension and surface concentration for binary systems In–Bi and Sn–Bi at 573 K. Data are obtained in situ with strict monitoring of the surface state via Auger electron spectroscopy and characteristic electron energy loss spectroscopy. It is shown that the surfaces of melts are enriched with bismuth throughout the range of volume concentrations.

铟，锡，铋和二元In-Bi和Sn-Bi合金的表面特性

摘要

通过分析获得液态的In，Sn，Bi和二元合金In–Bi和Sn–Bi的纯原子表面的不同方法，得出了结果。注意到特征电子能量损失谱对表面活性杂质的高灵敏度。In-Bi熔体的例子（Bi含量为6.16 at％）显示了氧对组分向表面层中的偏析的影响。结果是通过同时测量573 K下In-Bi和Sn-Bi二元体系的表面张力和表面浓度而得出的。通过俄歇电子能谱和特征电子能量损失能谱对表面状态进行严格监控，就地获得了数据。结果表明，在整个体积浓度范围内，熔体表面富含铋。
