Electrical properties of a single p-hexaphenylene nanofiber
The electrical characteristics of individual para-hexaphenylene (p6P) nanofibers with typical widths of a few hundred nanometers and heights of a few ten nanometers are investigated. For that purpose we transfer the narofibers onto a lithographically patterned silicon oxide electrode support structure. Individual nanofibers are contacted by titanium or gold electrodes and IV-curves are measured. The uncoated length of the nanofiber between contacts is from 600 to 900 nm. From a fit in the framework of a simple model, the mobility is found to be approximately 3(.)10(-2) cm(2) V-1 s(-1) for titanium contacts and 4(.)10(-2) cm(2) V-1 s(-1) for gold contacts.
