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…
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…
Spectral broadening in self-assembled GaAs quantum dots with narrow size distribution
Francesco Basso Basset, Sergio Bietti, Artur Tuktamyshev +3
The control over the spectral broadening of an ensemble of emitters, mainly attributable to the size and shape dispersion and the homogenous broadening mechanisms, is crucial to se…
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…
High-yield fabrication of entangled photon emitters for hybrid quantum networking using high-temperature droplet epitaxy
Francesco Basso Basset, Sergio Bietti, Marcus Reindl +7
Several semiconductor quantum dot techniques have been investigated for the generation of entangled photon pairs. Among the other techniques, droplet epitaxy enables the control of…
