Abstract
The elastic constants of single crystals of ZnTe and ZnSe (zinc‐blende type) have been determined over the temperature range 77°–300°K by means of the ultrasonic pulse‐echo method. The velocity of the longitudinal and two transverse waves propagated in the [110] direction showed 1%–1.4% increase at 77°K from the room‐temperature values and as a result, the elastic constants of both crystals showed 2%–3.5% increase at 77°K from the room‐temperature values. From the low‐temperature elastic constants, the Debye temperature was calculated to be 225.3°K for ZnTe and 278.5°K for ZnSe, respectively.This publication has 13 references indexed in Scilit:
