In this work, using the transfer matrix method and considering the Rashba spin-orbit interaction in the ZnSe/ZnMnSe/ZnSe/ZnMnSe/ZnSe heterostructures, the thickness effects of ZnMnSe and ZnSe layers on spin current density and shot noise is investigated. Results show that ZnMnSe thickness has a crucial role in spin polarization, in which spin current and shot noise for a spin up shows increasing with oscillation behavior while for a spin down shows a monotonically decreasing trend. Moreover, the effect of Rashba on spin up and spin down is to increase and decrease the height potential, respectively, which consequently causes to decrease and increase of spin current and shot noise in spin up and down, respectively.
Keywords: Shot noise, Diluted Magnetic Semiconductors, Rashba spin-orbit interaction.
