Modeling and Simulation for Current-Illumination Characteristics of Carbon Nanotube

According to the electronic structure characteristic of carbon nanotube (CNT) together with the corpuscular property and volatility of transport electron, the theoretical model of current-illumination characteristic of CNT was researched. The I-V characteristic of CNT was emulation calculated based on ATK modeling software. The electromagnetic scattering model and electromagnetic simulation of the CNT current-illumination absorptive character were researched on account of current-illumination characteristic of CNT discussed by classical electromagnetic theory. The simulation results indicate that, the electric current passed in CNT and the voltage at two sides of electrode have linear relation when 0-2v voltage is put on the Cu electrode of the two sides of CNT. When the voltage is above a certain number, the electric current reaches saturation. The Ti-Ti combination of electrode gets the maximum absorption power when it reaches the height of 300nm.
