Abstract:
1. A method for functionalizing a collection of carbon nanotubes (CNTs), the method comprising: irradiating a precursor gas to provide selected first target particles that contain N in a first chamber having a first selected sub-Torr chamber pressure p providing a collection of first target CNTs on a substrate in a second chamber having a second selected sub-Torr pressure p providing a particle communication mechanism that allows transport of at least a portion of the first target particles from the first chamber to the second chamber; allowing at least one first target particle to react with and become chemically attached to at least one first target CNT in the second chamber; and choosing a distance of transport d, of the at least one first target particle that is irradiated in the first chamber to at least one first target CNT in the second chamber, to lie in a first transport distance range, d<d
