Formation and characterization of carbon nanowires

Abstract

This article reports on the formation and electronic characteristics of conducting carbon nanowires produced by swift heavy ion irradiation of a fullerene thin film. This study shows that it is possible to create arrays of carbon nanowires, which are perfectly parallel to each other and perpendicular to the substrate. As-deposited fullerene films exhibit poor field emission characteristics with breakdown fields as high as 51 V / m, whereas low dose ion irradiated fullerene film produces a threshold field as low as 9 V / m. The present approach of making conducting carbon nanowires by ion irradiation for potential field emitters and large area applications is also discussed.

Fabrication of Fluorescent Nanowires via High-Energy Particles-Triggered Polymerization Reactions

“…In fact, we have reported a number of nanowires from various synthetic polymers and biomacromolecules [5][6][7][8][9]. In addition, it was demonstrated that nanowires were developed from small molecules based on π-conjugated molecules [14,15].…”

Nano tracks in fullerene film by dense electronic excitations

“…They reported that tracks should be formed above a threshold (dE/dx) e value of about 3-4 keV/nm. Although there have been a number of studies on damage of fullerene by ion beam [3,4,[7][8][9][10] indicating the possible formation of ion tracks, no direct evidence of tracks in fullerenes by microscopy techniques has been reported. The damage process under the dense electronic excitations in such a complicated systems needs to be investigated in more details.…”

“…The controlled conducting nano wire patterns formation in films by ion beam has been demonstrated [3,4]. Phase transformation of fullerene by ion beam has been a topic of fundamental research interests.…”

Optically transparent carbon nanowire thin film

“…So far, the CNWs have not been regarded as promising structures for nanoelectronic devices because of their poor electrical conductivity about 10 À1 cm À1 [6], though metallic CNWs were reported recently [7,8]. So far, concerns regarding nanowire thin films, having potential for diverse applications such as sensors and also large scale applications, have looked tremendous interest [9,10]. Therefore, it is worth conducting further systematic studies on CNWs.…”

“…Fortunately, a-CNW thin films were developed [9,10] and considered as potential building blocks for future miniaturised devices. However, the fabrications of these thin films with multiple-way junctions have not been reported so far.…”
