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...
This study examines the heat transfer enhancement attributes of carbon nanotubes (CNTs) applied to the bottom wall of a shallow rectangular micro-channel. Using deionized water as working fluid, experiments were performed with both a bare copper bottom wall and a CNT-coated copper wall. Boiling curves were generated for both walls, aided by high-speed video analysis of interfacial features. CNT arrays...
Applications that exploit the exceptional transport properties of carbon nanotubes (CNTs) at practical length scales almost invariably require good contact of the CNTs with the contacting surface. For example, vertically aligned and dense arrays of carbon nanotubes have been demonstrated to be good thermal interface materials. However, interfacial resistance to thermal and electrical transport between...
