Landau damping effects on the scattering spin-asymmetry and channel preference in election-hole plasmas

Abstract

The scattering spin-asymmetry and spin channel preference in electron collisions are investigated in electron-hole plasmas. It is found that the Landau damping effect enhances the scattering channel preference for the spin-singlet electron scattering and suppresses the spin-triplet electron scattering except the scattering angle theta = pi/2. It is also found that the spin-singlet electron scattering decreases with an increase of the quantum shielding distance. In addition, the Landau damping effect on the spin-asymmetry parameter is found to be more significant in the intermediate domain of the quantum Debye length. (C) 2012 American Institute of Physics.
