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…
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…
The role of the C2 gas in the emergence of C60 from the condensing carbon vapour
Shoaib Ahmad, Kashif Yaqub, Afshan Tasneem
A model has been developed that illustrates the emergence of C60 from the condensing carbon vapor. It is shown to depend upon the decreasing heats of formation for larger cages, ex…
