Peierls barriers of a-type edge and screw dislocations moving on basal and prismatic planes in magnesium
Exact shape of Peierls barriers are calculated for ⟨ a⟩ edge and screw dislocation gliding on basal and prismatic planes in magnesium by using of several popular interatomic potentials. Comparison of these potentials is performed in order to describe their abilities and limitations. Stability of dif...
