Abstract

Single-walled carbon nanotubes (SWCNTs) are used widely in fabricating nanoelectronic devices because of their unique electrical properties. In this paper, we report the fabrication of carbon nanotube field-effect transistors (CNTFETs)-based inverter and ring oscillator electronic circuits using the dielectrophoresis (DEP) method. The electrical property of fabricated CNTFET-based devices was measured. The CNTFET-based inverter shown electrical transfer characteristics, while the CNTFET-based ring oscillator demonstrated oscillation characteristics, denoting that the CNTFET-based circuits can function well for the application of electronic circuits. The DEP-based fabrication method is scalable, and could be used for the wafer-scale fabrication of carbon nanotube electronic circuits.
