Space-Filling Fractal Description of Ion-induced Local Thermal Spikes in Molecular Solid of ZnO
Shoaib Ahmad, Muhammad Yousuf
Anions of the molecules ZnO, O2 and atomic Zn and O constitute mass spectra of the species sputtered from pellets of molecular solid of ZnO under Cs+ irradiation. Their normalized…
Regenerative Soot-IX: C3 as the dominant, stable carbon cluster in high pressure sooting discharges
Sohail Ahmad Janjua, M. Ahmad, S. D. Khan +3
Results are presented that have been obtained while operating the graphite hollow cathode duoplasmatron ion source in dual mode under constant discharge current. This dual mode ope…
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…
Formation and transformation of low density, onion-like carbon cages
Shoaib Ahmad, Uzair Ahmed, Farrukh E. Mubarik +1
A novel growth technique for low density, non-icosahedral carbon onion-like structures on Cu surface is described. The technique differs with the formation of carbon onions inside…
Formation of carbon nano and micro structures on C1+ irradiated copper surfaces
Shoaib Ahmad
A series of experiments has identified mechanisms of carbon nano- and micro-structure formation at room temperature, without catalyst and in the environment of immiscible metallic…
Transition from the C3-dominated discharge to the sooting plasma
Shoaib Ahmad, Bashir Ahmad, Tasneem Riffat
Mass spectrometry and photoemission spectroscopy of a graphite hollow cathode source identify the parameters of the transition from the C(3) dominated discharge to the sooting plas…
