Information Processing with Pure Spin Currents in Silicon: Spin Injection, Extraction, Manipulation and Detection
Olaf M. J. van "t Erve, Chaffra Awo-Affouda, Aubrey T. Hanbicki +3
We demonstrate that information can be transmitted and processed with pure spin currents in silicon. Fe/Al2O3 tunnel barrier contacts are used to produce significant electron spin…
Large Nonlinear Kerr Angle in non-Centrosymmetric Fe/AlGaAs (001)Heterostructure
Haibin Zhao, Diyar Talbayev, Gunter Luepke +3
A large nonlinear magneto-optical effect is observed in a non-centrosymmetric Fe/AlGaAs (001) heterostructure. This effect is a direct consequence of interference between second-ha…
Determination of Interface Atomic Structure and Its Impact on Spin Transport Using Z-Contrast Microscopy and Density-Functional Theory
Thomas J. Zega, Aubrey T. Hanbicki, Steven C. Erwin +5
We combine Z-contrast scanning transmission electron microscopy with density-functional-theory calculations to determine the atomic structure of the Fe/AlGaAs interface in spin-pol…
Cross-sectional STM of Mn-doped GaAs: theory and experiment
J. M. Sullivan, G. I. Boishin, L. J. Whitman +3
We report first-principles calculations of the energetics and simulated scanning tunneling microscopy (STM) images for Mn dopants near the GaAs (110) surface, and compare the resul…
Epitaxial Growth of the Diluted Magnetic Semiconductors CryGe1-y and CryMnxGe1-x-y
G. Kioseoglou, A. T. Hanbicki, C. H. Li +3
We report the epitaxial growth of CryGe1-y and CryMnxGe1-x-y(001) thin films on GaAs(001), describe the structural and transport properties, and compare the measured magnetic prope…
Analysis of the Transport Process Providing Spin Injection through an Fe/AlGaAs Schottky Barrier
A. T. Hanbicki, O. M. J. van t Erve, R. Magno +7
Electron spin polarizations of 32% are obtained in a GaAs quantum well via electrical injection through a reverse-biased Fe/AlGaAs Schottky contact. An analysis of the transport da…
