The spin-dependent hole transport in the CdTe \(/\) CdMnTe heterostructure with double barriers and double δ-potentials is studied. Since the considered heterostructure is symmetric and no external field is applied, only the Dresselhaus spin–orbit interaction is included in the study. The transfer matrix method is used to analyse the spin-dependent transmission of holes. The double δ-potential height and the distance between them influence the transmission coefficient, polarisation efficiency and tunnelling time of the light holes (LH) and heavy holes (HH). The contrast in the response of LH and HH in terms of energy at which resonance occurs and polarisation efficiency are reported.
