Sažetak
An attempt is made to study the electronic contribution to elastic constants of degenerate ternary semiconductors on the basis of a newly derived dispersion law taking into account the influence of band tails. It is found, taking n-Hg1-xCdxTe as an example that mentioned contribution increases with increasing carrier degeneracy in different manner and that the formation of band tails decreases the contribution in both the cases. The corresponding results for well-known nondegenerate parabolic energy bands in the absence of any such tails have been obtained from our results under certain limiting conditions.
