Selective suspension in aqueous sodium dodecyl sulfate according to electronic structure type allows simple separation of metallic from semiconducting single-walled carbon nanotubes (2009, methodology): “For this r eason, separation of m- from s-SWNTs has become a fl ourishing subfi eld and in fact enrichment of m/s-SWNTs has been achieved by various techniques including (AC) dielectrophoresis [ 1 ], density gradient centrifugation [2], and (DC) agarose gel electrophoresis [3].”
Evaluating the impact of resistance in carbon nanotube bundles for VLSI interconnect using diameter-dependent modeling techniques (2006, methodology): “However, techniques such as alternating current dielectrophoresis have the potential to improve the proportion of metallic nanotubes within a bundle [ 21 ].”
