    Rashba Spin-Orbit interaction in Two-Dimension Electron Gas
    (Addis Ababa University, 2016-08) Gemechu, Belay; Senbeta, Teshome (PhD)
    We have studied the spin orbit-coupling from the Dirac equation, Understanding the properties of electronic states in quantum wires is a central issue in nanoscience. In the ballistic region, with low electronic densities, electron-electron interactions are not very important, and wire conductance is determined by the transmission of electrons as independent particles and the effects of spin-orbit interaction (SOI) on the energy bands,a system of two dimensional equations with respect to the spinor components "#(t), in the case of = 0, 6= 0 and ballistic conductance
