Nano tracks in fullerene film by dense electronic excitations
P. Kumar, D. K. Avasthi, J. Ghatak +3
In the present work, we investigate the formation of nano tracks by cluster and mono-atomic ion beams in the fullerene (C60) thin films by High Resolution Transmission Electron Mic…
Growth of narrow-neck, epitaxial and nearly spherical Ge nanoislands on air-exposed Si(111)-(77) surfaces
K. Bhattacharjee, A. Roy, S. Roy +4
Growth of narrow-neck, epitaxial as well as non-epitaxial and nearly spherical Ge islands on air-exposed Si(111)-(7\times7) surfaces has been investigated by in-situ scanning tunne…
Growth of epitaxially oriented Ag nanoislands on air-oxidized Si(111)-(7x7) surfaces: Influence of short range order on the substrate
Anupam Roy, K. Bhattacharjee, J. Ghatak +1
Clean Si(111)-(7{x7) surfaces, followed by air-exposure, have been investigated by reflection high energy electron diffraction (RHEED) and scanning tunneling microscopy (STM). Four…
MeV ion-induced strain at nanoisland-semiconductor surface and interfaces
J. Ghatak, B. Satpati, M. Umananda +4
Strain at surfaces and interfaces play an important role in the optical and electronic properties of materials. MeV ion-induced strain determination in single crystal silicon subst…
