title: High junction and twin boundary densities in driven dynamical systems.
abstract: A novel mechanism for the generation of device materials with very high domain boundary densities is described: we shear the sample in a computer experiment and achieve higher twin densities than in rapid quench. These domain patterns are very stable. Elastically soft materials (image with 6.4$ \times $10(5)  atoms) has greater twin densities than hard materials, even for nano-crystals.
