Surface Conductance Induced Dielectrophoresis of Semiconducting Single-Walled Carbon Nanotubes
Abstract
Dielectrophoresis on surfactant-stabilized single-walled carbon nanotube (SWNT) suspensions has been demonstrated to separate metallic from semiconducting tubes by their different electric field-induced polarizabilities. Here we report that the interaction between SWNTs and the surfactant induces a nanotube surface conductance which gives rise to a unique electric field frequency dependence of the nanotube dielectrophoresis. We observe a surfactant concentration dependent crossover frequency enabling separation of metallic from semiconducting SWNTs at high frequency and deposition of metallic and semiconducting SWNTs at low frequency − both being important aspects for building nanotube-based electronics. Moreover, the data demonstrate that the theoretical description of dielectrophoretic forces is valid beyond the dimensions of cells or viruses.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
