Uniaxially stressed germanium with fundamental direct band gap
R. Geiger, T. Zabel, E. Marin +17
We demonstrate the crossover from indirect- to direct band gap in tensile-strained germanium by temperature-dependent photoluminescence. The samples are strained microbridges that…

Interpretation of monoclinic hafnia valence electron energy loss spectra by TDDFT
Linda Hung, Cyril Guedj, Nicolas Bernier +3
We present the valence electron energy-loss spectrum and the dielectric function of monoclinic hafnia (m-HfO) obtained from time-dependent density-functional theory (TDDFT) pre…
