“…A variational procedure is frequently used to calculate the ground‐state binding energies which are found to be dependent on the system geometries, height, and thickness of potential barriers, and positions of an impurity. Currently, the effect of spin‐orbit interaction is included in CQWWs . It is found that the strength of the interaction, which causes energy splitting of spin up and spin down states, can control tunneling of electron wavefunctions through a potential barrier in CQWWs.…”

We propose a coaxial cylindrical quantum well wire which is composed of layers of a dilute magnetic semiconductor (DMS) and a nonmagnetic semiconductor (NMS). Using effective mass approximation, we present a numerical calculation of the eigenenergies and eigenstates of electrons in the heterostructure. The variation of the spin‐dependent energy levels is influenced by the giant Zeeman splitting and potential energies due to a vector potential for sufficiently low and high magnetic fields, respectively. It is found that crossing and anticrossing behaviors of energy levels can be controlled by the thickness of a NMS layer. The ballistic transport of the structure is also investigated. The ranges of the Fermi energy for obtaining full spin polarization are suggested in this work.
