Abstract :
A carbon nanotube (CNT) thermometer is reported that operates on the principles of electrical shot noise. Shot noise thermometry is a self calibrating measurement technique that relates statistical fluctuations in dc current across a device to temperature. A self-heating shot noise model has been developed and applied to experimental data to determine the thermal resistance of a CNT device consisting of an array of vertical CNTs supported in a porous anodic alumina template. The thermal resistance is found to be 1.5 *108 K/W.
