Anisotropy of ultrasonic waves propagation velocities in CdHgTe/CdTe

Abstract

The complete set of elastic moduli of Cd₀.₂Hg₀.₈Te was obtained. Taking into account elastic moduli found for Cd₀.₂Hg₀.₈Te and appropriate literary data for CdTe the anisotropy of velocities of volume and Rayleigh waves propagating on (100) and (110) boundaries was calculated. Finally, peculiarities of the anisotropy of SAW propagating velocities for each of components of layered structures CdHgTe/CdTe and for the heteroepitaxial structure as a whole were analysed.
