      Friction is usually associated with its obvious practical importance. This tends to emphasize the engineering aspects of friction and thereby hides the fact that there is a wealth of interesting physics involved, part of which cannot be regarded as fully understood at present. New techniques, such as friction force microscopy, have started to provide access to the phenomenon of friction on the atomic scale. This has given a strong impulse to the field of tribology, pushing it significantly beyond the engineering level and into the regime of the fundamental aspects of frictional energy dissipation. The Review Article by Krylov and Frenken (pp. 711–736) highlights the atomic-scale physics of friction, in particular in this relatively young and rapidly developing field of nanotribology. In this review, the authors concentrate on the specific case of dry, unlubricated contacts and they pay special attention to several non-trivial phenomena, such as superlubricity or orientational lubricity and thermolubricty, that can make such contacts super-slippery.

      Long-range crystal-lattice distortion fields of epitaxial Ge–Sb–Te phase-change materials (Phys. Status Solidi B 4/2014)

      Ferhat Katmis, Martin Schmidbauer, Sergiy M. Bokoch, Peter Rodenbach, Henning Riechert and Raffaella Calarco

      Article first published online: 22 APR 2014 | DOI: 10.1002/pssb.201470123

      Phase change materials (PCM), based on Ge-Sb-Te alloys, are among the most auspicious classes of materials for both optical and electrical storage applications. To further develop PCM technology for electrical memory, it is crucial to clearly identify the structural defects present in such alloys and further on to understand their role in electrical transport.

      Ferhat Katmis et al. (pp. 769–773) investigated the structural evolution of Ge-Sb-Te alloys by synchrotron-based X-ray scattering in situ during molecular beam epitaxy and also ex situ. The results reveal the formation and evolution of defect-induced inhomogeneities during growth. Long-range crystal-lattice distortion fi elds are generated by point defects formed during the growth with an average range of the distortion fi eld around the defect of about 2.5–3.0 nm and a pronounced fi eld anisotropy. In contrast to the well-known structural model, in which random occupation of Ge (octahedrally bonded), Sb, and vacancies on the cation site creates an isotropic distortion fi eld, the experimental results point to the presence of defects caused by a fraction of tetragonally bonded Ge atoms.
