US Patent 7763885 - Organic thin film transistor having surface modified CNTs

http://www.freepatentsonline.com/7763885.html

In organic transistors high contact resistances can result in an increase in driving voltages and inefficient operation. This patent from Samsung teaches how surface-modified carbon nanotubes can be used to alleviate this problem. Claim 1 reads:

1. A transistor structure comprising:

an organic semiconductor layer including surface-modified carbon nanotubes and an electrically-conductive polymer,

wherein the surface-modified carbon nanotubes have surfaces modified with a curable functional group, the curable functional group being directly bound to the carbon nanotubes through an oxygen atom of the curable functional group.
