Transient behavior of integrated carbon nanotube field effect transistor circuits and bio-sensing applications

In this work, a current transport model for the carbon nanotube field effect transistor has been built, which includes both static and dynamic behavior. A model of carbon nanotube as an interconnection in integrated circuits has also been presented, which is based on quasi one-dimensional fluid theory and combined with the current transport model of carbon nanotube field effect transistors to study the performance of carbon nanotube based integrated circuits. Verilog-AMS in combination with Cadence/Spectre has been used in characterizing carbon nanotube field effect transistors and all carbon nanotube based integrated circuits. It is shown through thionyl chloride and DNA detection at molecular levels that the transient behavior of carbon nanotube based circuits can be used for bio- and chemical sensing applications.
