Experimental and Theoretical Aspects of the Fragmentation of Carbon's Single and Multi-Walled Nanotubes
Sumera Javeed, Shoaib Ahmad
Energetic ion irradiation is an effective method for studying how single and multi-shelled carbon nanotubes break apart. The energy from ions is dissipated through both linear and…
Multi scaling of Fractal Dimension and Relative Entropy as Diagnostic Tools for Irradiated Carbon Nano-tubes
Shoaib Ahmad, Sumera Javeed
Linear and nonlinear dissipative structures emerge in the irradiated single and multi walled carbon nano-tubes in the form of collision cascades and thermal spikes. These are diagn…
Space-filling, multi-fractal, localized thermal spikes in silicon, germanium and zinc oxide
Shoaib Ahmad, Muhammad Sabtain Abbas, Muhammad Yousuf +3
The mechanism responsible for the emission of clusters from heavy ion irradiated solids is proposed to be thermal spikes. Collision cascade-based theories describe atomic sputterin…
An information theoretic model for the linear and nonlinear dissipative structures in irradiated single-walled carbon nanotubes
Afshan Ashraf, Sumera Javeed, Sumaira Zeeshan +2
Experiments with irradiated single-walled carbon nanotubes are shown to generate a set of probability distribution functions and to derive a set of information theoretic entropy-ba…
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…
