Non-local opto-electrical spin injection and detection in germanium at room temperature
Fabien Rortais, Carlo Zucchetti, Lavinia Ghirardini +13
Non-local carrier injection/detection schemes lie at the very foundation of information manipulation in integrated systems. This paradigm consists in controlling with an external s…
Germanium under high tensile stress: nonlinear dependence of direct band gap vs. strain
K. Guilloy, N. Pauc, A. Gassenq +15
Germanium is a strong candidate as a laser source for silicon photonics. It is widely accepted that the band structure of germanium can be altered by tensile strain so as to reduce…
Lattice strain and tilt mapping in stressed Ge microstructures using X-ray Laue micro-diffraction and rainbow-filtering
Samuel Tardif, Alban Gassenq, Kevin Guilloy +14
Micro-Laue diffraction and simultaneous rainbow-filtered micro-diffraction were used to measure accurately the full strain tensor and the lattice orientation distribution at the su…
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…
