Figure 2From: Ab-initiocalculations of spin tunneling through an indirect barrierThe transmission coefficient and its spin polarization for a GaAs/(AlAs)4/GaAs single barrier structure. The red solid line is for 'spin-up' and the blue dashed line is for 'spin-down'. Two cases of k|| are shown. Hot spots of large spin polarization exist in the vicinity of Fano resonances.Back to article page
