Abstract:We discuss the electron transport for a spin polarized current through a ballistic quantum nanojunction formed by two quantum dots (QDs) and a semiconducting quantum wire. We explore the possibilities of designing spintronic logic gates at the nano-scale level derivedfrom this device. Just one electron with a given spin polarization fills each QD and the stationary binary digit consists of the spin-up and spin-down of a single electron. Thus the spin polarizations of those electrons are treated as the two inpu… Show more
