Figure 2From: Linear Rashba Model of a Hydrogenic Donor Impurity in GaAs/GaAlAs Quantum WellsThe change in spin-orbit splitting energy Γ as the GaAs QW width increases when the hydrogenic donor impurity is at the QW center under the linear Rashba model along thez direction. The low to top lines correspond to the ground state (n = 0), the first excited state (n = 1), the second excited state (n = 2), and the third excited states (n = 3), respectivelyBack to article page
