In this study, spin polarization efficiency and spin-dependent transmission of electrons passing through a multiple quantum well structure with constant total effective length (60 nm) made of GaAs/Al_0.3Ga_0.7As, which was grown along [001] direction, were investigated. The calculations were done with the quantum transmitting boundary method. We presented the number of wells in a constant total length as a tuning tool for spin filtering purposes. In some energy intervals, 100% spin polarization and spin-dependent transmission were observed.

GaAs / Al 0.3 Ga 0.7 As多量子阱中的自旋滤波

在这项研究中，通过了沿[001]方向生长的GaAs / Al _0.3 Ga _0.7 As制成的具有恒定总有效长度（60 nm）的多量子阱结构的电子的自旋极化效率和自旋依赖性传输。调查。计算是用量子透射边界法完成的。我们介绍了恒定长度的孔数，作为用于自旋过滤目的的调整工具。在某些能量间隔内，观察到100％自旋极化和自旋依赖性透射。
