Carbon Nanotube Interconnects with Negative Temperature Coefficient of the Resistance

摘要

This paper demonstrates the possibility of obtaining interconnects with negative derivative of the electrical resistance with respect to temperature. The interconnect is made of multi-walled carbon nanotube, and is fabricated by self-assembly through a low-cost bottom-up technique. The results of an electro-thermal characterization demonstrate the possibility of obtaining a negative temperature coefficient of the electrical resistance and validate the theoretical model here adopted to justify such a behavior.
