US Patent 7189455 - Carbon nanotube/nanocrystal heterostructure


In order to create useful electronic structures from nanotubes they need to be connected to other electrical elements. This patent from the State University of New York teaches how to manufacture a nanotube/nanocrystal mixture wherein the nanotubes are linked to the nanocrystals via oxygen mediated covalent bonding so as to create a nanostructure more easily integrated in electronic systems. Claim 1 reads:

1. A fused heterostructure comprising a carbon nanotube and at least one nanocrystal, wherein the nanocrystal is directly attached by a covalent linkage to at least one oxygen moiety on the nanotube, and wherein there is no intermediary linker between the nanotube and the nanocrystal.
