Abstract
The spin-polarized transport properties of multiterminal silicene nanodevices are studied using the tight binding model and Landauer-Buttier approach. We propose a four-terminal â -shaped junction device and two types of three-terminal T-shaped junction devices, which are made of the crossing of a zigzag and an armchair silicene nanoribbon. If the electrons are injected into the metallic lead, the near-perfect spin polarization with 100% around the Fermi energy can be achieved easily at the other semiconducting leads. Thus the multiterminal silicene nanodevices can act as controllable spin filters.
