Native defect assisted enhanced response to CH4 near room temperature by Al0.07Ga0.93N nanowires
Santanu Parida, A. Das, Arun K. Prasad +2
Gas sensors at low operating temperature with high sensitivity are the demand for the group III nitrides owing to their high chemical and thermal stability. The CH4 sensing is real…
Ion induced segregation in gold nanostructured thin films on silicon
J. Ghatak, P. V. Satyam
We report a direct observation of segregation of gold atoms to the near surface regime due to 1.5 MeV Au2+ ion impact on isolated gold nanostructures deposited on silicon. Irradiat…
Flux dependent 1.5 MeV self-ion beam induced sputtering from Gold nanostructured thin films
J. Ghatak, B. Sundaravel, K. G. M. Nair +1
We discuss four important aspects of 1.5 MeV Au2+ ion-induced flux dependent sputtering from gold nanostrcutures (of an average size 7.6 nm and height 6.9 nm) that are deposited on…
Ion beam induced enhanced diffusion from gold thin films in silicon
J. Ghatak, B. Sundaravel, K. G. M. Nair +1
Enhanced diffusion of gold atoms into silicon substrate has been studied in Au thin films of various thicknesses (2.0, 5.3, 10.9 and 27.5 nm) deposited on Si(111) and followed by i…
Flux dependent MeV self-ion- induced effects on Au nanostructures: Dramatic mass transport and nano-silicide formation
J. Ghatak, M. Umananda Bhatta, B. Sundaravel +5
We report a direct observation of dramatic mass transport due to 1.5 MeV Au2+ ion impact on isolated Au nanostructures of an average size 7.6 nm and a height 6.9 nm that are deposi…
Observation of a Universal Aggregation Mechanism and a Possible Phase Transition in Au Sputtered by Swift Heavy Ions
P. K. Kuiri, B. Joseph, H. P. Lenka +4
Two exponents, , for size distribution of -atom clusters, , have been found in Au clusters sputtered from embedded Au nanoparticles under swift heavy ion irr…
