Abstract
The effects of gas adsorption and collisions on the thermopower and resistivity of mats of tangled single-walled nanotube (SWNT) bundles were studied. SWNT samples were prepared by lightly pressing the fibrous powder into thin pellets or mats. Thermoelectric (S) data were collected using a heat pulse technique. The four-probe resistance (R) was measured in a van der Pauw geometry using a lock-in amplifier by a standard low frequency ac method. Results indicate that the transport properties of SWNT bundles are sensitive to even inert gases present in the sample chamber.
