. -- Samples of single-wall carbon nanotubes containing tubes with an "armchair" wrapping have been produced and exhibit metallic behavior with an intrinsic resistivity which increases approximately linearly with temperature over a wide temperature range. Here we study the coupling of the conduction electrons to long-wavelength torsional shape fluctuations, or twistons. A one-dimensional theory of the scattering of electrons by twistons is presented which predicts an intrinsic resistivity proportional to the absolute temperature. Experimental measurements of the temperature dependence of the resistivity are reported and compared with the predictions of the twiston theory. Since the discovery of carbon nanotubes in 1993 [1], [2] there has been interest in these structures as prototypical molecular wires. Research in this direction has been given additional impetus by the recent discovery of a new catalytic route to the synthesis of single-wall carbon nanotubes (SWNTs) [3]. In this proc..
