title = "Ge-Based Spin-Photodiodes for Room-Temperature Integrated Detection of Photon Helicity",
abstract = "Spin-photodiodes based on Fe/MgO/Ge(001) heterostructures are reported. These devices perform the room-temperature integrated electrical detection of the spin polarization of a photocurrent generated by circularly polarized photons with a wavelength of 1300 nm, for light pulses with intensity I 0 down to 200 μW. A forward and reverse-biased average photocurrent variation of 5.9% is measured for the complete reversal of the incident light helicity. Copyright {\textcopyright} 2012 WILEY-VCH Verlag GmbH & Co.
