摘要：

The thermal expansion coefficient variations in Hg1-xCdxTe (MCT) and Hg1-xZnxTe (MZT) are analyzed between 4 and 280 K. The phonon density of states (DOS) is modelled with seven Einstein peaks whose weight is adjusted to fit the specific heat variations. The mean Gruneisen coefficient associated with each peak is then deduced from a fit of the experimental linear thermal expansion coefficients. The variation with x of these Gruneisen coefficients allows to compare the bond strengths in MCT and MZT. A better stability of MZT as compared to MCT is deduced.
