Efficient electrical spin injection from a magnetic metal/tunnel barrier contact into a semiconductor
(2002)We report electrical spin injection from a ferromagnetic metal contact into a semiconductor light emitting diode structure with an injection efficiency of 30% which persists to room temperature. The Schottky barrier formed ...

Efficient spin detection across the hybrid Co/GaAs schottky interface
(2007)The electron spin detection efficiency was studied across Co/GaAs structures using photoexcitation techniques. Two sets of samples were prepared where the substrate surface was pretreated by annealing prior to growth for ...
