Shear response of Fe-bearing MgSiO(3) post-perovskite at lower mantle pressures
{{output}}
We investigate the shear response of possible slip systems activated in pure and Fe-bearing MgSiO(3) post-perovskite (PPv) through ab initio generalized stacking fault (GSF) energy calculations. Here we show that the [100](001) slip system has the easiest resp... ...
