A significant negative differential conductance (NDC) phenomenon of a bundle of single-walled nanotube (SWNT) at room temperature was conducted. Room-temperature negative differential conductance phenomenon was observed in a bundle of SWNT in a CNT based field effect transistor (CNTFET). The room temperature SWNT-NDC could be useful for practical applications of fast switching, oscillator and amplifying devices. It was suggested that the conductance variation of the SWNT and the shift of the energy level in the quantum well were responsible for the peak voltage shifts from 9.2 V to 7.8 with decreasing the gate voltage from 6 V to -6V.
