Abstract yambo is an open source project aimed at studying excited state properties of
condensed matter systems from first principles using many-body methods. As input, yambo …

Nanostructures in silicon (Si) induced by phase transformations have been investigated
during the past 50 years. Performances of nanostructures are improved compared to that of …

High-quality defect-free lonsdaleite Si and Ge can now be grown on hexagonal nanowire
substrates. These hexagonal phases of group-IV semiconductors have been predicted to …

Recent advances in the synthetic growth of nanowires have given access to crystal phases
that in bulk are only observed under extreme pressure conditions. Here, we use first …

Hexagonal Si allotropes are expected to enhance light absorption in the visible range as
compared to common cubic Si with diamond structure. Therefore, synthesis of these …

In the past decades, group IV nanowires and nanoparticles have been the subject of
extensive research. Beside tremendous progress in morphological control and integration in …

Advances in the fabrication and characterization of nanowires polytypes have made crystal
phase engineering a well-established tool to tailor material properties. In this review, recent …

Semiconducting nanowires (NWs) offer the unprecedented opportunity to host different
crystal phases in a nanostructure, which enables the formation of polytypic heterostructures …

Silicon nanowires have been grown by a plasma-assisted vapour–liquid–solid method
using tin as the catalyst. Transmission electron microscopy in the [110] zone axis shows that …

Hexagonal SiGe is a promising material for combining electronic and photonic technologies.
In this paper, the energetic, structural, elastic, and electronic properties of the hexagonal …
