Quantum Peierls stress of straight and kinked dislocations and effect of non-glide stresses

Autor: Barvinschi, B., Proville, L., Rodney, D.

It was recently shown that to predict reliable Peierls stresses from atomistic simulations, one has to correct the Peierls barrier by the zero-point energy difference between the initial and activated states of the dislocation. The corresponding quan
