WebMay 30, 2003 · The laser light lifts electrons from the valence band into the conduction band, where they travel freely when a voltage is applied to the semiconductor. And if the laser is polarized in just the right way, the flowing electrons will all spin in the same direction. But two laser beams acting in concert can pull off an even niftier trick. WebFeb 2, 2024 · In this Letter, we show how such a spin-polarized relativistic beam can be produced by ionization injection of electrons of certain atoms with a circularly polarized …

WebMar 11, 2024 · The spin polarization increases with decreasing 2DEG density, suggesting that Coulomb interactions are a key aspect of the symmetry breaking. We propose that … WebMar 14, 2013 · Scientists from the Berkeley Lab discovered that when topological insulators are hit with a laser beam, the spin polarization of the electrons they emit can be … WebFeb 18, 2011 · The spin polarization observed for electrons transmitted through a monolayer of 78-bp DNA is shown for cw (Fig. 3A) and ccw (Fig. 3C) circularly polarized light, and for linearly (Fig. 3B) polarized light. The average polarizations are P= −(55 ± 7)%, −(61 ± 6)%, and −(57 ± 6) %, respectively, again nearly independent of the light polarization. shushi canning vale
