Spin injection and detection up to room temperature in Heusler~alloy/-GaAs spin valves
T. A. Peterson, S. J. Patel, C. C. Geppert +7
We have measured the spin injection efficiency and spin lifetime in CoFeSi/-GaAs lateral nonlocal spin valves from 20 to 300 K. We observe large (40 V) spin valve s…
Gold assisted molecular beam epitaxy of Ge nanostructures on Ge(100) Surface
A. Rath, J. K. Dash, R. R. Juluri +2
We report on the gold assisted epitaxial growth of Ge nanostructures under ultra high vacuum (UHV) conditions (\approx3\times 10-10 mbar) on clean Ge (100) surfaces. For this study…
Shape evolution of MBE grown SiGe structures on high index Si(5 5 12) surfaces: A temperature dependent study
J. K. Dash, A. Rath, R. R. Juluri +1
The morphological evolution and the effect of growth temperature on size, orientation and composition of molecular beam epitaxy grown Ge-Si islands on Si(5 5 12) surfaces have been…
Structural modification in Au/Si(100) system: Role of surface oxide and vacuum level

Universality in Shape Evolution of SiGe Structures on High Index Silicon Surfaces
J. K. Dash, T. Bagarti, A. Rath +2
The MBE grown SiGe islands on reconstructed high index surfaces, such as, Si(5 5 12), Si(5 5 7) and Si(5 5 3) show a universality in the shape evaluation and the growth…
Growth of Oriented Au Nanostructures: Role of Oxide at the Interface
Ashutosh Rath, J. K. Dash, R. R. Juluri +3
We report on the formation of oriented gold nano structures on Si(100) substrate by annealing procedures in low vacuum (\approx10-2 mbar) and at high temperature (\approx 975^{\cir…
