Self Aligned Multi-Layer Electrodes with Nano-Gap for Fluidic and Magnetic Assembly of Carbon Nanotubes
نویسندگان
چکیده
A self aligned nano scale gap between multiple metal layers has been fabricated using a newly developed technique of controlled undercut and metallization (CUM), and applied for the assembly of an individual carbon nanotube (CNT). The new method enables conventional optical lithography to fabricate nano-gap electrodes and self aligned patterns with nano scale precision. Individual CNTs were assembled over the fabricated nano-gap electrodes by the fluidic assembly using magnetic attraction on a residual catalyst. This work may allow the mass production of selfassembled carbon nanotubes for nano electronic devices or biosensors.

Suspended multiwalled carbon nanotubes as self-aligned evaporation masks.
We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

In the present study, we investigate the potentiometric behavior of Cu2+ carbon paste electrodes based on two mercapto compounds 2-Ethylmino-5-Mercapto-1,3,4-Thiadiazole (EAMT) and 2-Acetylamino-5-mercapto-1,3,4-thiadiazole (AAMT) self-assembled on gold nano-paricle (GNP) as ionophore. Then, the results obtained from the modified electrodes are compared. The self-assembled ionophores exhibit a ...

We exploit the remarkable low-friction bearing capabilities of multiwalled carbon nanotubes (MWNTs) to realize nanoelectromechanical switches. Our switches consist of two open-ended MWNT segments separated by a nanometer-scale gap. Switching occurs through electrostatically actuated sliding of the inner nanotube shells to close the gap, producing a conducting ON state. For double-walled nanotub...

Supercapacitor (SC) is an energy storage technology that bridges the gap between conventional capacitors and rechargeable batteries. Emerging nano-architectured carbon–metal oxide composites are promising for electrode designs for supercapacitors due to their unique strategy utilizing electrochemical double-layer capacitance (EDLC) and pseudo-capacitance together in single cell to optimize the ...
متن کاملFunctionalized Carbon Nanotubes Produced by APCVD using Camphor
A simple chemical vapor deposition technique at atmospheric pressure (APCVD) is adopted to synthesize the aligned arrays of functionalized multi-walled carbon nanotubes (AMWCNTs) without using any carrier gas, at 230◦C, 750◦C and 850 ◦C. Camphor (C10H16O) is used as carbon source because this botanical hydrocarbon is chip and abundant which convert the CVD technique to a green method for produc...
