By fabricating a few charge storages around the single-walled carbon nanotube (SWNT) channel of a Fabry–Perot quantum interference device (FPD), we have succeeded in detecting the single-charge transition from the channel to the charge storages. In addition, storage energy was controlled by an applied bias. An abrupt discrete switching of the source-drain current was observed in the electrical measurements of the SWNT FPD. These random telegraph signals (RTS) are attributed to charge fluctuating traps charge near the conduction channel. Moreover, drain current with RTS increased stepwise with increasing applied gate voltage, which is attributed to modulation of the channel by a single charge induced in the charge storage near the channel by the applied gate voltage. The current-switching behavior associated with the occupation of individual charge traps was analyzed statistically.
