Abstract
This invention relates to a semiconductor array having a first semiconducting layer and a second semiconducting layer made of a ferromagnetic material, which is coupled to the first semiconducting layer in such a way that a spin-polarized state of the semiconducting charge carriers is injected into the first semiconducting layer. The second semiconducting layer interacts with charge carriers made available outside of the second semiconducting layer in such a way that a high spin polarization is created in the second semiconducting layer at least 250 Kelvin.
