First-principles study of the high-temperature phase of Li2NH

First-principles study of the high-temperature phase of Li2NH

On the basis of ab initio molecular dynamics simulations, we propose that the Fm3̄m symmetry of the high-temperature (above 356 K) phase of Li 2NH results from dynamical disorder due to fast diffusion of Li interstitials and a slower diffusion of Li vacancies. Still, most of the NH groups point tetr...
