@article{ISI:000225478600131, abstract = {New experimental results, and a plausible theoretical understanding thereof, are presented for the flow-induced currents and voltages observed in single-walled carbon nanotube samples. In our experiments, the electrical response was found to be sublinear-nearly logarithmic-in the flow speed over a wide range, and its direction could be controlled by an electrochemical biasing of the nanotubes. These experimental findings are inconsistent with the conventional idea of a streaming potential as the efficient cause. Here we present Langevin-equation based treatment of the nanotube charge carriers, assumed to be moving in the fluctuating field of ions in the flowing liquid. The resulting ``Doppler-shifted″ force-force correlation, as seen by the charge carriers drifting in the nanotube, is shown to give a sublinear response, broadly in agreement with experiments.}, article-number = {205423}, author = {Ghosh, S and Sood, AK and Ramaswamy, S and Kumar, N}, doi = {10.1103/PhysRevB.70.205423}, issn = {1098-0121}, journal = {PHYSICAL REVIEW B}, month = {NOV}, number = {20}, orcid-numbers = {GHOSH, SUSMITA/0000-0002-1691-761X Ghosh, Shankar/0000-0003-3617-5390}, researcherid-numbers = {Kumar, Narendra/B-6083-2009 }, times-cited = {50}, title = {Flow-induced voltage and current generation in carbon nanotubes}, unique-id = {ISI:000225478600131}, volume = {70}, year = {2004} }
