Abstract
We study the conductivity of thin films of molybdenum oxide (MoOx) mixed with an organic hole transport material, such as N,Nâ²-bis(naphthalen-1-yl)-N,Nâ²-bis (phenyl)benzidine or 4â²,4â³-tri(N-carbazolyl)triphenylamine, in lateral test devices. Contrary to previous reports, the conductivity of the mixture is found to exceed that of neat MoOx, exhibiting ~Â 5 orders of magnitude higher conductivity in comparison to the neat films. Studies also show that the mixing enhances both hole and electron transport. The higher conductivity may be attributed to a higher concentration of “free” carriers in the mixture, as a result of the formation of a charge transfer complex between the MoOx and the hole transport material. The findings shed light on the potential of hybrid composites of inorganic and organic materials in realizing enhanced conductivity.
