Abstract Systems with non-trivial topological phases have insulating bulk, but exhibit channels of the conductivity located at the surface (or edge for a 2D system), which is a property of the topology of the system. Since the surface states are protected by this topology, the channel of the conductivity are free from backscattering, which makes the topological insulators ideal for application in spintronics. The realization of a spintronic device type transistor using topological insulators is not trivial, because there are inherent difficulties in achieving the transport measurements. In this project, we will studied the ballistic electron transport in systems with non-trivial topological phases, proposing a system that has the electronic conditions to enable the construction of a digital transistor using spin as a basic element for control of the transport properties of the system.
