Tailoring semiconductor spintronics devices [Elektronische Ressource] : tools for the creation and control of spins in two-dimensional electron gases / Matthias Scheid

In recent years the research field of semiconduc-tor spintronics has attracted considerable atten-tion. This interest was fueled by the prospect of spin-based devices, which could possess en-hanced functionalities compared to conventional charge-based microelectronics. However, in or-der to realize the building blocks for semiconduc-tor spintronics devices a number of fundamental obstacles have to be overcome. To this end, this thesis discusses several spin- related phenomena in two-dimensional electron gases, which can either be exploited as sources for spin currents/accumulations or which can be used for the efficient control of those spins. To Matthias Scheidbe specific, it deals with coherent electron trans-port through wire geometries in the presence of Tailoring semiconductor spin-orbit interaction and/or magnetic fields. For the numerical calculations a powerful quantum spintronics devices: transport code was used. The topics investigated in this thesis include spin ratchets, the phenom- Tools for the creation and enon of current-induced spin accumulation and finally quantum interference spin phenomena in control of spins in two-disordered systems.
