Photoelastic Behaviour

An analysis of the photoelastic behaviour of diatomic crystals is presented on the basis of the shell model including the effect of exchange charge polarizations. The strain derivatives of the electronic polarizabilities and dielectric constants calculated for alkali halides, MgO, ZnS, and CdS crystals compare well with the available experimental data.

Static Dielectric Constants

A quantitative form of the linear correlation between the high-frequency and static dielectric constants in ANB8-N (N = 2, 3) tetrahedrally coordinated semiconductor materials, and also in I-VII group alkali halides was studied. So, a quasi-linear relationship was found between the high-frequency and the static dielectric constants for some selected II-VI (ZnS, ZnSe, ZnTe and CdTe) and III-V (AlP, AlAs, AlSb,….etc) cubic zincblende type materials, in the other side a weak uphill linear relationship has been found in the case of I-VII (LiF, NaF, LiCl,….etc) group alkali halides compounds. In the case of II-VI and III-V cubic zincblende semiconductors, the linear regression is established with a correlation coefficient ( ) of about 0.98. The significance of the linear regression is given as the probability P <0.0001 of the null hypothesis.
