Assembly and Photo-Electric Properties of Interconnected Bundle Networks of Multi-Walled Carbon Nanotubes
Abstract:With this study, an approach to engineering of new air-suspended and interconnected networks of bundled nanotubes is introduced and demonstrated based on multi-electrode dielectrophoretic assembly. The network engineered from monodisperse multi-walled nanotubes that were vapor-deposited inside the pores of alumina templates are found to be mechanically stable, highly conductive and non-rectifying. The photo-conduction tests have further revealed a moderate light sensitivity attributed to photocarrier generation in individual tubes. A model to explain both the effect of photocurrent saturation that has been observed at larger intensities and the photocurrent–voltage dependences is presented and discussed. The engineered nanotube networks are expected to be suitable for a plethora of applications ranging from optical detection, electro-chemical/analyte sensing to scaffolds for tissue engineering and bio-medical research.
