Ferroelectric control of the spin texture in germanium telluride
C. Rinaldi, S. Varotto, M. Asa +9
The electrical manipulation of spins in semiconductors, without magnetic fields or auxiliary ferromagnetic materials, represents the holy grail for spintronics. The use of Rashba e…

Optical spin injection and spin lifetime in Ge heterostructures
F. Pezzoli, F. Bottegoni, D. Trivedi +9
We demonstrate optical orientation in Ge/SiGe quantum wells and study their spin properties. The ultrafast electron transfer from the center of the Brillouin zone to its edge allow…
