First-principles insight in structure-property relationships of hexagonal Si and Ge polytypes
Martin Keller, Abderrezak Belabbes, Jürgen Furthmüller +2
Hexagonal SiGe is a promising material for combining electronic and photonic technologies. In this work, the energetic, structural, elastic and electronic properties of the hexagon…
Giant optical oscillator strengths in perturbed hexagonal germanium
Abderrezak Belabbes, Friedhelm Bechstedt, Silvana Botti
We present ab initio calculations of electronic and optical properties of perturbed hexagonal germanium and demonstrate that it is a superior material for active optoelectronic dev…
Hund's rule-driven Dzyaloshinskii-Moriya interaction at 3d-5d interfaces
A. Belabbes, G. Bihlmayer, F. Bechstedt +2
Using relativistic first-principles calculations, we show that the chemical trend of Dzyaloshinskii-Moriya interaction (DMI) in 3d-5d ultrathin films follows Hund's first rule with…
