Abstract

We have investigated electronic transport in single-wall carbon nanotubes attached to multiple electrodes. Resistance measurement using a pair of electrodes with different gaps enabled separate evaluation of nanotube resistivity and contact resistance. We found that the resistivity depends on nanotube diameter. Electrodes with gold or palladium exhibit similar contact resistance with an order of 10kΩ. Contact resistance is insensitive to back gate voltage, contrary to the Schottky-barrier transistor model. We also demonstrated the top-down control of diameter and position of Fe catalysts by means of “lithographically anchored nanoparticle synthesis (LANS)” for nanotube growth. Chemical vapor deposition by using these patterned particles successfully produced single-wall carbon nanotubes.
