• On the symmetry of phosphorous doped ZnSe

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.

• Optical, thermal and phase transition studies in Sn1–𝑥Ge𝑥Te

The optical and thermal properties of the mixed semiconducting alloy, Sn1–𝑥Ge𝑥Te, is studied by photo acoustics, for various Ge concentrations and phase transition for a particular concentration is also studied by the same method. The results are compared with the available literature values and discussed.
