Growth and characterization of planar hexagonal Ge on CdS
Andrea Besana, Veronica Regazzoni, Marco Faverzani +13
Hexagonal group-IV semiconductors have attracted increasing interest owing to their unconventional electronic and optical properties compared to the cubic diamond phase. However, t…
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…
Optical spin pumping in silicon
Stefano Achilli, Damiano Marian, Mario Lodari +5
The generation of an out-of-equilibrium population of spin-polarized carriers is a keystone process for quantum technologies and spintronics alike. It can be achieved through the s…
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…
THz Higher-Order Topological Photonics in Ge-on-Si Heterostructures
Ian Colombo, Pietro Minazzi, Emiliano Bonera +2
We design germanium-based higher-order topological cavities for terahertz applications by breaking the symmetry of a two-dimensional photonic crystal following the Su-Schrieffer-He…
High-temperature droplet epitaxy of symmetric GaAs/AlGaAs quantum dots
Sergio Bietti, Francesco Basso Basset, Artur Tuktamyshev +3
We introduce a high-temperature droplet epitaxy procedure, based on the control of the arsenization dynamics of nanoscale droplets of liquid Ga on GaAs(111)A surfaces. The use of h…
