ABSTRACT
Thermal annealing after preamorphization and solid-phase epitaxy of ultrashallow B implants leads to deactivation and diffusion driven by interstitials released from end-of-range defects. F inhibits these processes by forming small clusters that trap interstitials. A competing B–F interaction causes deactivation when F and B profiles overlap. Both pathways suppress B transient enhanced diffusion.

    The interaction of Ni films with epitaxially grown Si-capped and not capped Si0.75Ge0.25 layers on Si(100) at 500 °C leads to the formation of NiSi1-uGeu films as a bilayer NiSi on NiSi0.75Ge0.25 with a rather clear compositional boundary. In the absence of a Si cap at the surface,...

    The formation of target patterns in oscillatory CO oxidation on Pt(110) is studied using laser-induced, controlled creation of temperature heterogeneities. For the first time, inward traveling target waves are observed in this reaction-diffusion system. The experimental results are compared to...

    The integral encounter theory (IET) has been extended to the reactions limited by diffusion along the reaction coordinate to the level crossing points where either thermal or hot electron transfer occurs. IET describes the bimolecular ionization of the instantaneously excited electron donor D*...

    A 100-nm-thick Fe50Pt50 film with high coercivity was fabricated by magnetron sputtering. On introducing a Cr top/bottom layer, the ordering temperature (Tor) of the film decreased considerably from 500 to 380 °C. On introducing both Cr top/bottom layer and a 0.2-nm-thick Cu interlayer, the...

    The stability limits in binary fluid mixtures are investigated on the basis of the global phase diagram approach employing a model for the attracting hard-sphere fluid. In addition to the diffusion spinodals the mechanical spinodals are included. As a result one finds topologically different...
