Thermal spikes induced sublimation of carbon nanotubes
Sumera Javeed, Shoaib Ahmad
We report and provide justification for the consistently observed four experimental facts of the mass spectrometric data of carbon cluster emission from the low-energy Cs irradiate…
Dynamics of fragmentation and multiple vacancy generation in irradiated single-walled carbon nanotubes
Sumera Javeed, Sumaira Zeeshan, Shoaib Ahmad
The results from mass spectrometry of clusters sputtered from Cs+ irradiated single-walled carbon nano-tubes (SWCNTs) as a function of energy and dose identify the nature of the re…
Amorphous carbon films in direct current magnetron sputtering from regenerative sooting discharge
Sumera Javeed, Sumera Yamin, Sohail Ahmad Janjua +6
We present results of carbon coatings on metal substrates in cylindrical hollow cathode (CHC) direct current magnetron sputtering. This is a new technique of making amorphous carbo…
Cs+ sputtered clusters from multi-walled carbon nanotubes and graphite
Shoaib Ahmad, Sumera Javeed, Sumaira Zeeshan +6
Experiments with multiwalled carbon nanotubes and graphite as targets in a source of negative ions with cesium sputtering have shown that nanotubes with nanometer radii and microme…
Irradiation induced vacancy creation in single walled carbon nanotubes
Sumera Javeed, Sumaira Zeeshan, Shoaib Ahmad
Single walled carbon nanotubes of 2 nm diameter and 3 to 13 micro meter length were compressed in Cu bullets and irradiated with positive ions of Cs with energies from 0.2 to 2.0 k…
Mass spectrometric identification of C60 fragmentation regimes under energetic Cs+ bombardment
Sumaira Zeeshan, Sumera Javeed, Shoaib Ahmad
Three C60 fragmentation regimes in fullerite bombarded by Cs+ are identified as a function of its energy. C2 is the major species sputtered at all energies. For E(Cs+) < 1 keV C2 e…
