Extended Data Fig. 4: Mechanism leading to anomalous slip.

A network formed by \({{\bf{b}}}_{1}\) and \({{\bf{b}}}_{2}\) screw dislocations in P₁₂ plane is intersected by dislocations \({{\bf{b}}}_{3}\) which glide in the principal slip system. The interaction results in the creation of highly mobile junctions, leading to long-distance glide of \({{\bf{b}}}_{1}\) and \({{\bf{b}}}_{2}\) dislocations in a single P₁₂ plane and of \({{\bf{b}}}_{3}\) and \({{\bf{b}}}_{4}\) dislocation in many parallel slip P₃₄ planes.
