The mean square displacements (MSD) of the neighbours around a vacancy in HgTe and CdTe are worked out using Green's function technique and scattering wave formalism. The results are compared with the values of the perfect systems. The phonon resonance due to the vacancy for the above systems are also simultaneously worked out.
