description: This surface is the result of a Molecular Dynamics simulation of bi-axial compression of single crystal Au. The initial configuration was an Au cube with side length 100 nm. The x- and y-directions of the simulation cell were parallel to the [-110] and [-1-12] directions of the crystal, respectively. The z-direction was parallel to the [111] crystal direction. The x- and y-directions were periodic, but the z-direction was free, hence the crystal had free surfaces along z. The present surface is the free surface in positive z-direction. The surface was initially an atomically flat (111) facet, but roughened by plastic deformation. The crystal was deformed with a rate of 1e8 s^-1 at a temperature of 100K. The temperature was controlled using a Dissipative Particle Dynamics thermostat. This dataset contains the surface at 30% engineering strain (side length ca. 70.1 nm). The simulations have been reported in the following publication: Hinkle, A. R.; Nöhring, W. G.; Leute, R.; Junge, T.; Pastewka, L.
