摘      要：Electron energy levels and positron states have been calculated for cadmium and zinc chalcogenide compounds within the pseudo-potential approach and the independent particle ***,the present contribution deals with the electron and positron chemical potentials allowing the calculation of the positron affinity to different materials of interest and hetero-structures formed by these ***,we here determine the positron diffusion constant by means of the positron deformation *** attempt has been made to scale positron affinity and diffusion constant with the lattice constant and the band gap energy,*** scaling is found to be not *** information gathered by the present study is of prime importance for a better understanding of positron trapping at interfaces and precipitates and should be useful in slow positron beam experiments.
