Formation of C-centers in Si-based systems by light ion irradiation
Carolina Crosta, Riccardo Nardin, Patrick Daoust +8
Atomic-scale crystal defects in Si are quantum-light sources offering tantalizing integration with existing photonic technologies. Yet, the controlled creation of near-infrared col…
Giant spin-to-charge conversion in germanium tin epilayers
S. Oyarzún, C. Gonzalez-Fuentes, Erick Burgos +4
We report a study of the spin-to-charge current conversion in compressively strained Ge1-xSnx alloy epilayers as a function of the Sn concentration by means of the inverse spin Hal…
Optical control of the spin-Hall effect in a two-dimensional hole gas
Simone Rossi, Valentina Caprotti, Andrea Filippi +5
Relativistic effects influence the motion of charged particles in solids by intertwining spin and momentum. The resulting phenomena exhibit rich and intriguing properties that can…
Photoluminescence study of interband transitions in few-layer, pseudomorphic, and strain-unbalanced Ge/GeSi multiple quantum wells
M. Montanari, M. Virgilio, C. L. Manganelli +11
In this paper we investigate the structural and optical properties of few strain-unbalanced multiple Ge/GeSi quantum wells pseudomorphically grown on GeSi reverse-graded substrates…
