Analysis of the transport process providing spin injection through an Fe/AlGaAs Schottky barrier
(2003)Electrical injection through a reverse biased Fe/AlGaAs Schottky contact was used to obtain electron-spin polarizations in a GaAs quantum well. The analysis of the transport data using the Rowell criteria shows that ...

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 ...

Electron spin filtering in ferromagnet/semiconductor heterostructures
(2003)Circularly polarized light was used to generate spin-polarized electrons at room temperature in ferromagnet (FM)/GaAs Schottky diode structures. A change in the helicity-dependent photocurrent was obtained when the ...

Highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor structures
(2004)The highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor (SC) structures was discussed. It was found that the photocurrent was dependent on the relative alignment of the light helicity ...

Numerical calculation model for spin-dependent transport of photoexcited electrons across Fe/GaAs(0 0 1) interfaces
(2010)abs Spin-dependent transport of photogenerated electrons across Fe/GaAs(0 0 1) interfaces is calculated using a one-dimensional electron transport model. Creation of spin-polarized electrons by photoexcitation in this model ...

A schottky tunnel barrier contact for electrical spin injection from a magnetic metal into a semiconductor
(2003)A study was performed on a Schottky tunnel barrier contact for electrical spin injection from a magnetic metal into a semiconductor. It was reported that spin injection from a Fe Schottky contact produced a spin polarization ...
