From pseudo-direct hexagonal germanium to direct silicon-germanium alloys
Pedro Borlido, Jens Renè Suckert, Jürgen Furthmüller +3
We present ab initio calculations of the electronic and optical properties of hexagonal SiGe alloys in the lonsdaleite structure. Lattice constants and electronic band structures i…
Efficient strain-induced light emission in lonsdaleite germanium
Jens René Suckert, Claudia Rödl, Jürgen Furthmüller +2
Lonsdaleite germanium has a direct band gap, but it is not an efficient light emitter due to the vanishing oscillator strength of electronic transitions at the fundamental gap. Tra…
Direct Bandgap Emission from Hexagonal Ge and SiGe Alloys
E. M. T. Fadaly, A. Dijkstra, J. R. Suckert +16
Silicon crystallized in the usual cubic (diamond) lattice structure has dominated the electronics industry for more than half a century. However, cubic silicon (Si), germanium (Ge)…
Efficient approach to solve the Bethe-Salpeter equation for excitonic bound states
F. Fuchs, C. Rödl, A. Schleife +1
Excitonic effects in optical spectra and electron-hole pair excitations are described by solutions of the Bethe-Salpeter equation (BSE) that accounts for the Coulomb interaction of…
