    • Abstract


      The site symmetry of P doped ZnSe is analysed in detail here, as the recent experiments suggest two possible symmetries $T_d$ and $C_{3V}$. The reduction to $C_{3V}$ is attributed to the presence of natural impurity, Ga. Our calculations based on molecular model and Green’s functions suggest that the symmetry $C_{3V}$ is possible with ZnSe : P when Jahn Teller distortion of about ∼ 0.2 Å (towards one of Zn atom) is assumed. This has been supported by other experiments.
