Nano carbon devices and applications

In this paper, three kinds of devices and applications of nano carbon materials, i.e., carbon nanotube and graphene are introduced. 1) Using the feature of the nanostructure of carbon nanotube, quantum nano memory which can store the single charge one by one at the interface of the all arounded double stacked gate insulator was realized. 2) Only by modulating the gate bias, the particle nature and the wave nature of electron can be controlled, and Kondo resonance state was realized. 3) First selective bio sensor was realized using the aptamer modified graphene FET with high sensitivity.
