We report the modification of the transport, optical and electrical properties of 200 nm thick N, N'-diphenyl-N, N'-bis(3-methylphenyl)- 1,1'biphenyl-4,4' diamine (TPD) films on indium-tin oxide (ITO) when a low density of acid oxidized single-walled carbon nanotubes (o-SWCNTs) are present at the ITO/TPD interface. Most significantly, current - voltage measurements show strong evidence for a change from contact to bulk limited transport. We postulate that these observations result from a change in the structure of the TPD film seeded by the presence of o-SWCNTs at the ITO surface.
