Claim:
1. A structure having a carbon nanotube (CNT) layer, the structure comprising: a substrate having a first region arranged adjacent to and in contact with a second region, the first region comprising a metal oxide, the second region comprising a non-metal oxide, and the first region having a first isoelectric point that is greater than a second isoelectric point of the second region; a self-assembled monolayer arranged only on the first region, the self-assembled monolayer comprising a precursor molecule comprising a first functional group to anchor the precursor molecule to the substrate and a second functional group having a first ionic charge moiety on a surface of the self-assembled monolayer; and a CNT layer on the self-assembled monolayer, each CNT of the CNT layer comprising a second ionic charge moiety that bonds to the first ionic charge moiety; wherein the CNT layer has a density exceeding 1 CNT per square micron, and top surfaces of the second region of the substrate remaining exposed.
