摘要：
We report the controllable resistance of multiwalled carbon nanotube bundles for the possible application in nanoscale electronics. The resistance as well as the variation of resistance with temperature depends on the bundle diameter. The larger the diameter, smaller is the resistance and weaker is the variation of resistance with temperature that make the bundles advantageous in nanoscale electronics and in some other applications. As the resistance and the variation can be controlled by monitoring the bundle diameter, the temperature dependency of resistance can be employed in temperature thermometry.
