Carrier and Spin Coherent Dynamics in Strained Germanium-Tin Semiconductor on Silicon
Sebastiano De Cesari, Andrea Balocchi, Elisa Vitiello +6
Germanium-Tin is emerging as a material exhibiting excellent photonic properties. Here we demonstrate optical initialization and readout of spins in this intriguing group IV semico…
Optically reconfigurable polarized emission in Germanium
Sebastiano De Cesari, Roberto Bergamaschini, Elisa Vitiello +2
Light polarization can conveniently encode information. Yet, the ability to steer polarized optical fields is notably demanding but crucial to develop practical methods for data en…
Giant g factor tuning of long-lived electron spins in Ge
Anna Giorgioni, Stefano Paleari, Stefano Cecchi +5
Control of electron spin coherence via external fields is fundamental in spintronics. Its implementation demands a host material that accommodates the highly desirable but contrast…
Spin-dependent direct gap emission in tensile-strained Ge films on Si substrates
E. Vitiello, M. Virgilio, A. Giorgioni +7
The circular polarization of direct gap emission of Ge is studied in optically-excited tensile-strained Ge-on-Si heterostructures as a function of doping and temperature. Owing to…
