Paper Abstract

We successfully fabricated single electron transistors (SETs) operating at room temperature with carbon nanotube (CNT) channel having different island sizes. The fabrication of the CNT SETs is performed by electrical manipulation using non-contact mode atomic force microscope (AFM). We carried out cutting or nicking of CNTs by applying negative voltage between a metal-coated AFM tip and CNT. A precise control over the CNT dot size was achieved by changing the nicking distance and CNT SETs with a dot size of 15 and 22 nm were fabricated. By changing the size of the dot we could arbitrarily change the operation characteristics of the device where the period of oscillations increases as the dot size decreases.
