  • Abstract
    A new forming spin injection barrier method on the GaAs-based two-dimensional electron gas (2-DEG) system was utilized using CoFe as the ferromagnetic electrodes. It was shown that the novel method of oxidation process enables to easily control the oxide thickness by the amount of growing AlAs layer and obtain a pin-hole free quality.
