"Negative TCR"

Electrical Properties of Yarned Carbon Nanotube Fiber Resistors
Youngtaek Lim, Sunwoo Lee
J Electr Electron Mater 2017;30(1):59-62.   Published online January 1, 2017
CNT (carbon nanotube) resistors with low resistance and negative TCR (temperature coefficient of resistance) were fabricated with yarned CNT (carbon nanotube) fibers. The CNT fibers were prepared by yarning CNTs grown on the silicone substrate by CVD (chemical vapor deposition) method. The CNT resistors were fabricated by winding CNT fibers on the surface of ceramic rod. Both metal terminals were connected with the CNT fiber wound on the ceramic rod. We measured electrical resistance and thermal stability with the number of CNT fibers wound. The CNT resistor system shows linearly decreased resistance with the number of CNTs wound on the ceramic rod and saturated at 20 strands. The CNT resistor system has negative TCR between -1,000 ~ -2,000 ppm/℃ and stable frequency properties under 100 kHz.
