| Abstract: | The ultrasonic phonon-viscosity loss and thermo-elastic loss have been studied in octahedral semiconductors along< 100>, <110> and <111> crystallographic directions as a function of high temperature (=300K). For this evaluation, the temperature dependence of second- and third-order elastic constants starting with two basic parameters has been computed. The thermo-elastic loss is very small as compared to phonon-viscosity loss. The behaviour of temperature dependence of ultrasonic attenuation is the same as in other semiconducting materials. |
