Application of Carbon nano tube field-effect transistor as sensor in analyzing of integrated circuits

The purpose of this investigation is to develop a current-transport model for Carbon nano tube field effect transistor applicable in the analysis of detection of chemical material. We implemented an efficient numerical model of a Carbon nano tube field-effect transistor with regard to ultrasonic nano welding treatment. Our results have shown a strong dependence of the I-V characteristics on the wrapping angle and diameter of Carbon nano tubes. Also our calculations have indicated that Carbon nano tube field effect transistors based sensors are promising compact ultra-sensitive and ultra low-power advanced miniaturized sensors in comparison to conventional sensors.
