Light Element Quantification in Irradiated Nanostructured Ferritic Alloys

As the local electrode atom probe, and almost all previous generations of instruments, use a time-of-flight mass spectrometer, atom probe tomography (APT) is able to detect, and in most cases quantify, all elements. However, an appropriate pulse repetition rate for the field evaporation pulse, and the associated timing window, must be selected to detect the entire range of elements present. Hen...

Molecular-dynamics study of surface segregation in liquid semiconductor alloys

We report the results of a molecular-dynamics study of the surface tension and surface profile of liquid Si and Ge (l -Si and l -Ge! and their alloys using empirical Stillinger-Weber potentials. The calculations are carried out at two temperatures slightly above the melting temperatures of Si and Ge and the alloys Si 0.8Ge 0.2 and Si 0.2Ge 0.8 . They show clear evidence of surface segregation b...
