    Development of Cross-Hatch Morphology During Growth of Lattice Mismatched Layers

    An approach is developed for understanding the cross-hatch morphology in lattice mismatched heteroepitaxial film growth. It is demonstrated that both strain relaxation associated with misfit dislocation format...

    Thermoelectric Properties as a Function of Electronic Band Structure and Microstructure of Textured Materials

    A tool has been developed at Fraunhofer-IPM to calculate the transport properties of thermoelectric material by using its band structure described in terms of effective masses and the location of the ellipsoid...

    Evolution of Coherent Interphase Boundaries during Annealing of Multilayers: A Monte Carlo Study

    Some properties of nanoscale multilayers, as for example the giant magnetoresistance, are expected to depend sensitively on the structure of the interphase boundaries. Recent experimental work aimed to elucida...

    Thermally Induced Changes of Interphase Boundary Morphology in Coherent A/B Multilayers: A Monte Carlo Simulation

    The evolution of the interphase boundary morphology during annealing of nanoscale metallic A/B multilayers is studied by means of Monte Carlo simulations based on a vacancy migration algorithm. The two compone...

    Modeling of Microstructure Development in Nanoscale Layered Systems

    The composition evolution in nanoscale layered systems during annealing is considered within the framework of the Cahn-Hilliard theory. Starting from as-deposited multilayers with morphologically rough and che...

    Fracture mechanisms and strength of thin films

    Mechanisms for residual stress evolution in thin films are discussed. For the examples of thermally grown oxide layers on intermetallic alloys and boron nitride films it is shown how structure heterogeneity in...

    On the theory of the central peak at structural phase transitions

    A universal mechanism is proposed, which explains the appearance of the central peak by means of a transition from ergodic to nonergodic dynamical behaviour of the system at some temperatureT g
