In non-close-packed crystalline lattices, e.g. of bcc metals and intermetallic compounds, the stress-state dependence of the Peierls barrier for the motion of a screw dislocation violates Schmid's law and leads to non-associated plastic flow at the continuum level. Plasticity models based upon disti
## Abstract Photoconductivity spectra and Hallβeffect measurements of deformed Si samples with different doping concentrations and dislocation densities suggest a dependence of the dislocation energy levels on their occupation. This is in contrast to the widely used rigidβbandβmodel. A Peierlsβlike
