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…
Disentangling nonradiative recombination processes in Ge micro-crystals on Si substrates
F. Pezzoli, A. Giorgioni, K. Gallacher +9
We address nonradiative recombination pathways by leveraging surface passivation and dislocation management in micron-scale arrays of Ge crystals grown on deeply patterned Si subst…
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…
Spin photovoltaic cell
F. Bottegoni, M. Celebrano, M. Bollani +4
Spintronics, which aims at exploiting the spin degree of freedom of carriers inside electronic devices, has a huge potential for quantum computation and dissipationless interconnec…
