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…
Dynamic and Static Transmission Electron Microscopy Studies on Structural Evaluation of Au nano islands on Si (100) Surface
Ashutosh Rath, R. R. Juluri, P. V. Satyam
Transmission electron microscopy (TEM) study on morphological changes in gold nanostructures deposited on Si (100) upon annealing under different vacuum conditions has been reporte…
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…
Temperature-dependent electron microscopy study of Au thin films on Si (100) with and without native oxide layer as barrier at the interface
Ashutosh Rath, J. K. Dash, R. R. Juluri +2
Real time electron microscopy observation on morphological changes in gold nano structures deposited on Si (100) surfaces as a function of annealing temperatures has been reported.…
Nano scale phase separation in Au-Ge system on ultra clean Si(100) surfaces
Ashutosh Rath, J. K. Dash, R. R. Juluri +4
We report on the formation of lobe-lobe (bi-lobed) Au-Ge nanostructures under ultra high vacuum (UHV) conditions (\approx 3\times 10^{-10} mbar) on clean Si(100) surfaces. For this…
