Optical Spin Orientation
and the analog amplifier can apply voltage with the maximum frequency 2MHz. In combination with a λ/4 wave plate one can excite the sample with right and left handed circular polarization. The EOM and AOM [...] t. In QDs, the main source of electron spin decoherence is its interaction with a large number (10 4 –10 6 ) of nuclear spins thus representing a “nuclear spin bath” acting on the electron spin. In many [...] fields cause a precession of electron spins, which eventually leads to electron spin relaxation [3, 4]. Because of the large number of nuclei coupled to the electron, the nuclear spin bath presents a formidable …
