In this research project we present a novel manufacturing process which is able to fabricate sub-10nm metallic gratings. It utilizes CNTs as a wire-cutting tool to remove the tiny metallic materials and fabricates the metallic gratings. The strategy is to embed the CNTs into the metallic material first, and then steer one ends of the CNTs upward with a constant velocity, CNTs will behavior like a...
This research studied the environment temperature affect to alcohol detecting and heated carbon nanotube film after alcohol detecting for a good chemical sensor application. The results showed that at the environment temperature below the room temperature (in this work −5 °C), the percentage of resistance changing is 15.70 % while at the 85 °C is 3.35 %. The heated CNT film after alcohol absorption...
The principle of gas-flowing assistant growing of carbon nanotube is described in this paper. The effect of gas-flow was analyzed with numerical simulation, which can give some instruction for the self-aligned growth of carbon nanotube. Scanning electronic microscopy (SEM) images demonstrate that the self-aligned carbon nanotube can be realized by a gas-flowing CVD process and the distribution of...
The carrier transport in carbon nanotube is studied using the nonequilibrium Green's function with the self-consistent approximation methods. The model provides the basis for ATK software to simulate the electron transfer characteristics. The I–V characteristic of the carbon nanotube based device was simulated with ATK software. The electrical properties of the device formed by individual nanotube...
