Design and application of carbon nanotube FETs

Carbon nanotube has many extraordinary electrical properties and extensive application foreground on nano electronics.With the development of nanotechnology,new process technique is generated.And the bottom-up fabrication process is developed based on nano technique and nano materials,then various new electron devices is constructed by using the properties of nanotubes and nanowires.Since the CNTs can act same roles in electronic circuit as Si material,and with the profound development of research of nano-ICs based on CNTs,the electronics will turn into the nanoelectronic era truly from the microelectronic era.In this paper,the feature of typical structure of nano electronic devices based on CNTs,CNTs field effect transistor（FET）,is discussed,the characteristic of typical structure of logic-gate circuits based on CNT-FETs is represented,and the application of CNTs on flexible nano ICs is also described.
