AbstractWe study spin injection from an in-plane magnetized Fe thin layer into a GaAs/AlGaAs quantum well (QW) in low magnetic fields of ±0.37 T using oblique Hanle effect. An oblique low magnetic field induces the precession of electron spins in the GaAs QW, allowing us to detect the spin polarization of electrons injected across the Fe/AlGaAs interface. Our analysis of the circular polarization of light emitted in the electron-hole recombination process in the QW gives an estimate of the lower bounds of the spin polarization to be 4.0%. Also, a spin lifetime of 140 psec is obtained in this analysis, indicating that spin depolarization at the Fe/AlGaAs interface is more predominant rather than spin relaxation in the QW region.

Complete Understanding

Recent progress in the application of scanning tunneling microscopy (STM) and tunneling spectroscopy (STS) to oxide surfaces has allowed issues of image formation mechanism and spatial resolution limitations to be addressed. As the STM analyses of oxide surfaces continues, it is becoming clear that the geometric and electronic structures of these surfaces are intrinsically complex. Since STM requires conductivity, the oxides in question are transition metal oxides that accommodate aliovalent dopants or nonstoichiometry to produce mobile carriers. To date, considerable effort has been directed toward probing the structures and reactivities of ZnO polar and nonpolar surfaces, TiO2 (110) and (001) surfaces and the SrTiO3 (001) surface, with a view towards integrating these results with the vast amount of previous surface analysis (LEED and photoemission) to build a more complete understanding of these surfaces. However, the spatial localization of the STM/STS provides a level of detail that leads to conclusions somewhat different from those made earlier.
