FIG. 1.

RHEED patterns of the MgO layer and the CoFe after annealing at for the samples with the MgO thickness of (a) 1.5, (b) 2.0, and (c) 2.5 nm along the azimuths of and and [(d)–(f)] the corresponding high-resolution TEM images of the samples. Insets: low-magnification TEM images. The zone axis is parallel to the [110] direction of Ge.

FIG. 2.

(a) characteristics of tunnel contacts with the 1.5, 2.0, and 2.5 nm MgO at RT. Left inset: schematic diagram of the sample structure. Right inset: curves with linear scale up to ±0.5 V. (b) Arrhenius plots of the tunnel contacts with the different MgO thicknesses. Inset: SBHs and RA products of the tunnel contacts at each reverse bias. (c) Schematic energy band diagram of the contact. The CNL and density of interface states are depicted in red and blue, respectively.

Image of FIG. 3.
FIG. 3.

(a) Vertical and (b) lateral geometry of FM/TB/SC/TB/FM structure.(c) lateral geometry of FM source/SC/FM drain structure. (b) Calculated local spin signal of the vertical geometry and (d) nonlocal spin signal of the lateral geometry as a function of RA product and TSP of the contact. Center inset shows parameters and their values used in this calculation. The solid and dashed lines represent experimental results for the tunnel contacts at reverse bias (spin injection for local/nonlocal observation) and forward bias (spin detection/spin extraction for local/nonlocal observation), respectively.
