Abstract: The dynamics of solid state dewetting phenomena of a 50nm thick, mazed bicrystalline Al film on single crystalline α-Al2O3(sapphire) substrates was studied in-situ using an environmental scanning electron microscope (ESEM). The bicrystalline Al thin films… read more here.

Abstract: We study the propagation of dissipative structures in inhomogeneous media with a focus on pinning and depinning transitions. We model spatial complexity in the medium as generated by dynamical systems. We are thus able to… read more here.

Abstract: We investigate the formation of localized domains through front pinning in a periodically forced, bistable semiconductor laser with long-delayed optoelectronic feedback. At difference with 1D spatially extended systems, the transition from the pinning to the… read more here.
