Elastic debye temperature of compounds with sphalerite structure

Elastic Debye temperatures θ EL of the semiconducting compounds A III B V , A II B VI and CuCl are evaluated from second order elastic constants C ik available from the literature. The dependence of θ EL on temperature is given. The results at 0 K are compared with those calculated from low temperature measurements of specific heat. Generally, the agreement between these values is better than found in the literature up to now.
