      abstract     = {The separation of solids in adhesive contact, or the
                      fracture of solid bodies, often results in the emission of
                      high-energy photons, e. g., visible light and X-rays. This
                      is believed to be related to charge separation. We propose
                      that the emission of high-energy photons involves surface
                      roughness and surface diffusion of ions or electrons,
                      resulting in the concentration of charge at the tips of high
                      asperities, and to electric-field enhancement, which
                      facilitate the discharging process which result in the
                      high-energy photons. If the surface diffusion is too fast,
                      or the separation of the solid surfaces too slow,
                      discharging starts at small interfacial separation resulting
                      in low-energy photons. Copyright (C) EPLA, 2010},
