The kinetic theory of gases is applied to analyze slow translational motion of low-concentration particles driven by an external force in a homogeneous gas. The analysis takes into account the diffusion due to the difference in acceleration between p

The electron density of tetragonal ZnP2 and Cdh2 has been calculated by the pseudopotential method. The valence band of ZnP2 and CdP2 consists of 48 subbands grouped into 4 subbands. The Zn(Cd)−P bond proved to be ionic-covalent, with a bond charge

Phonon spectra of (GaAs)n(Ga1−x AlxAs)m superlattices were calculated using the Keating model with allowance made for long-range forces. The calculated summed longitudinal acoustical branches are consistent with observed experimental Raman doublets
