Abstract
An analysis of effective compressibilities in ionic semiconductors PbS, PbSe, PbTe and SnTe has been performed within the framework of many-body lattice theory (MLT). The extended three-body force shell model (ETSM) has been employed to obtain the values of effective compressibilities in the solids under study. The model parameters have been calculated using the expressions for elastic and dielectric constants within the framework of the ETSM. It is found that the predicted values of β ∗/β agree fairly well with the results obtained from the Szigeti relation.
