Upper Bounds to Carbon Nanotube Thermal Conduction and Entropy Flow

Quantum upper bounds to thermal conductance are computed for zigzag single walled carbon nanotubes of different diameters. Upper bounds to energy and entropy flow are also computed. The results impose a stringent limit on the maximum values that any experiment or simulation could obtain. Some previous theoretical simulations have violated the theoretical maxima.Copyright © 2005 by ASME
