Therefore, it has been shown that bulk modulus of these compounds can be evaluated by using two parameters i.e. average inter-atomic distance and melting temperature rather than a number of parameters and constants as used by previous workers so far. On the basis of this result a simple bulk modulus-microhardness relationship is proposed and used to estimate the microhardness of these semiconductors. The results obtained by the proposed approach are in close agreement with the experimental data and shows a systematic trend. 收起
