Abstract:This thesis is devoted to silicon-based spintronic devices, and describes the investigation of the issues for the development of such devices, and provides solutions towards realization thereof. By combining ferromagnetic properties and semiconductor characteristics and using the spin of the electron, semiconductor-based spintronics opens up the possibility to realize novel electronic devices. One example is the silicon spin-MOSFET, a gate-controlled magneto-resistive device with a silicon channel and a ferromagnetic source and drain, in which the channel conductance can be modulated by the relative alignment of the source and drain magnetization. Silicon is most attractive as the material for the semiconductor channel not only because of its use in mainstream semiconductor technology, but also because Si is expected to have a long spin lifetime.
