Dendrite fragmentation by catastrophic elastic remelting

S. Ananiev, P. Nikrityuk, K. Eckert

The paper proposes a new fragmentation mechanism of dendrite arms. The theoretical basis of this mechanism is a shift in the thermodynamical equilibrium at the solid-liquid interfa…

Ab initio study of element segregation and oxygen adsorption on PtPd and CoCr binary alloy surfaces

Arezoo Dianat, Janina Zimmermann, Nicola Seriani +3

The segregation behavior of the bimetallic alloys PtPd and CoCr in the case of bare surfaces and in the presence of an oxygen ad-layer has been studied by means of first-principles…

Spiral Growth and Step Edge Barriers

A. Redinger, O. Ricken, P. Kuhn +4

The growth of spiral mounds containing a screw dislocation is compared to the growth of wedding cakes by two-dimensional nucleation. Using phase field simulations and homoepitaxial…

Shaping single walled nanotubes

Alberto Zobelli, Alexandre Gloter, Chris P. Ewels +1

We show that electron irradiation in a dedicated scanning transmission microscope can be used as a nano-electron-lithography technique allowing the controlled reshaping of single w…

Structural and magnetic properties of Mn-implanted Si

Shengqiang Zhou, K. Potzger, Gufei Zhang +9

Structural and ferromagnetic properties in Mn implanted, p-type Si were investigated. High resolution structural analysis techniques like synchrotron X-ray diffraction revealed the…
