A general approach is outlined to predict the chemical compositions of solute nanoclusters embedded in materials with nearly free electrons. Based on the experimental results of the two-dimensional angular correlation of positron annihilation radiation and the corresponding theoretical calculations, we show that the Fermi surface (FS)-Brillouin zone interaction is a key to understand the chemical composition realized in solute nanoclusters because the presence of FS necks at zone boundaries causes a reduction in electron energy due to the band-gap effect.
