摘要
Current transport in carbon nanotube field effect transistors (CNT-FETs) has been modeled from charge distributions and the potential inside the carbon nanotube. Analytical equations describing I-V characteristics of the CNT-FETs have been obtained from the combination of diffusion and drift mechanisms in the channel region for normal and subthreshold operations. It is shown that the electronic transport in semiconducting single-walled carbon nanotubes and field effect transistors can provide better understanding of their bio- and chemical sensing for the detection of traces of agents at molecular levels.
