Abstract
We have carried out firstprinciples calculations to investigate the structural stability of the Zr x Al1−x N for several x values in sodium chloride and wurtzite structures The Density Functional Theory DFT such as is implemented in the wien2k code was used and its is found that for x05 a transition phase induced by pressure exists The pressures that induce the transition are about 133 60 and 067 GPa for x=0 1/4 and 1/2 respectively However for x05 such transition does not exist Graphs of Density of States DOS for pressures across the transition are obtained and relevant electronic features are discussed
