Spin Injection in Ferromagnet/ Semiconductor Hybrid Structures
We review our recent studies on transport phenomena in hybrid structures which consist of a ferromagnetic metal and a high-mobility two-dimensional electron system (2DES). The main focus will be on our recent investigations on ballistic spin injection into semiconductors. A novel fabrication technique by means of cleaved-edge overgrowth is used to generate lateral spin-valve devices with clean interfaces and deep-sub-µm 2DES channel length.
