摘要：

The pressure induced phase transition and relative volume change, of partially covalent AlAs compound have been investigated by means of two different models (i) interaction potential model (IPM) (ii) modified interaction potential model (MIPM) which includes covalency and zero point energy effects in the previous (IPM) model. It is found that the inclusion of covalency and zero point energy effects in MIPM has improved the results and show a good agreement with available experimental data.
