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…
Nanodot to Nanowire: A strain-driven shape transition in self-organized endotaxial CoSi2 on Si (100)
J. C. Mahato, Debolina Das, R. R. Juluri +4
We report a phenomenon of strain-driven shape transition in the growth of nanoscale self-organized endotaxial CoSi2 islands on Si (100) substrates. Small square shaped islands as s…
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
A. Rath, J. K Dash, R. R. Juluri +1
To understand surface structural modifications for Au/Si (100) system, a thin gold film of ~2.0 nm was deposited under ultra high vacuum (UHV) condition on reconstructed Si surface…
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…
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…
