Abstract

In this study based on Green’s function formalism, we explore some aspects of the spin-dependent properties of a triple-quantum-dot ring structure. In this structure, one of the quantum dots has been considered to be non- magnetic and the Rashba spin-orbit interaction is imposed locally on this dot while the two others can be magnetic. Besides, it can be controlled the interference of electron waves in the output leads by tuning the parameters containing on-site energy of quantum dots, the magnetic flux penetrating inside the ring, the magnetic moment of dots and the Rashba spin-orbit interaction. The optimum parameters may lead to perfect splitting and polarization and simulate the Stern-Gerlach aparateus.
