Graphitic oxide-induced enhanced electrical conductance in CuTCNQ nanorod film

We demonstrate a simple method to increase the conductance of CuTCNQ nanorod film, using graphitic oxide. CuTCNQ nanorods are grown by a chemical method on prepatterned electrodes on glass substrate and as-grown nanorods are used to measure I-V at room temperature. The electrical conductance of CuTCNQ are then modified by graphitic oxide (GO) by dispersing it onto film of CuTCNQ nanorods. The conductance of the nanorod film is increased by approximately one order in magnitude. Increase in conductance occurs due to electronic charge transfer from graphitic oxide to CuTCNQ, which has been corroborated from the observed frequency shift of C≡N stretching mode, as seen in Fourier Transform Infrared Spectroscopy (FTIR).
