Abstract: Abstract High-index Si and Ge surfaces are used for growth of low defect density epitaxial layers and for nanostructure growth. In this work an atomic structure model of the high-index Ge(3 3 1)-5 × 1 surface is developed on… read more here.

Abstract: Helium (He) is a typical impurity element and plays a crucial role in the microstructural evolution in nuclear materials under irradiation. Here, we systematically investigate the interactions between He and self-interstitial atoms (SIAs) as well… read more here.
