Abstract
AbstractThe empirical pseudopotential method has been applied to study electronic band structures of BeTe and ZnTe. The band‐structure calculations are performed to study the electron momentum density distribution also in the two semiconductors. The electron momentum distribution is studied in terms of Compton profiles computed along [100], [110], [111], [210], [211] and the [221] directions. The autocorrelation functions have also been computed along the principal crystallographic directions. The band‐by‐band decomposition of autocorrelation functions and the directional Compton profiles are presented. The results are interpreted in terms of band structure. The spherically averaged Compton profile of ZnTe is compared with the available experimental data. On the basis of theoretical anisotropies in the Compton profiles and autocorrelations, bands, bonds and momentum density build up in BeTe and ZnTe semiconductors are discussed.
