“…In particular, in two and three envelopes with the addition of one and two extra B seeds, respectively. Terkhi and collaborators found an analogous behavior for the transmission probability in AlGaAs/GaAs superlattices [26]. The G ⇑⇓ τzsz s are suppressed in the energy interval 3.0∆ so < ∆ z < 3.6∆ so , see the shaded strip in figures 3(b), (d) and (f).…”

“…In the case of AlGaAs/GaAs semiconductor superlattices, extended unit cells in monomer, dimer, and trimer fashion are an alternative for band gap engineering due to the possibility of duplicate, triplicate, and in general multiply the number of minibands and minigaps in a specific energy region [26]. In the case of monomer superlattices the unit cell is composed of two dissimilar barriers alternated with two quantum wells.…”

Monomer, dimer and trimer semiconductor superlattices are an alternative for bandgap engineering due to the possibility of duplicate, triplicate and in general multiply the number of minibands and minigaps in a speciﬁc energy region. Here, we show that monomer, dimer and trimer magnetic silicene superlattices (MSSLs) can be the basis for tunable magnetoresistive devices due to the multiplication of the peaks of the tunneling magnetoresistance (TMR). In addition, these structures can serve as spin-valleytronic devices due to the formation of two well-deﬁned spin-valley polarization states by adjusting appropriately the superlattice structural parameters. We obtain these conclusions by studying the spin-valley polarization and TMR of monomer, dimer and trimer MSSLs. The magnetic unit cell is structured
