MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
متن کاملHydrogen-induced magnetism in carbon nanotubes
Spin-polarized density functional theory is used to investigate hydrogen-induced magnetism in single-walled carbon nanotubes SWNTs . Hydrogen trapped at a carbon vacancy can trigger delocalized electron spin polarization on semiconducting zigzag SWNTs. Hydrogen pinned by a carbon adatom on the surface of the SWNT can induce spin polarization localized at the carbon adatom, independent of the di...

متن کاملElongation of arrays of amorphous carbon tubes
Due to its special properties, amorphous carbon (a-C) materials have been reported to display novel functions for many potential optical [1,2], frictional [3] and electronic [2,4] applications. These include protective coating, ultra durable anti-reflection coatings [1,2], mechanical devices [2,3], and electron emitters [4]. The ability to fabricate a-C into desired physical shapes has attracte...
متن کاملEffects of Nanoscale Clustering in Amorphous Carbon
In this review the effects of clustering associated with the sp and sp phases of amorphous carbon thin films are examined. We highlight that many of the optical and electronic properties of these films can be explained by consideration of disorder in the sp phase. Within the context of topological and structural disorder, we explain the variation of the visible Raman line width, Raman shift, Ta...
