Rashba spin–orbit interaction (RSOI) in two-dimensional electron gas is illustrated. When electron wave transmits through a semiconductor heterojunctions, spin flip and spin birefringence occur at the interface. According to the continuity conditions, we study how incident angle or the strength of spin–orbit interaction affects the scatter coefficients. Totally reflection of spin-up chirality is explained. This work will enlighten proposals of spin devices for spin filtration.
