Carbon nanotube (CNT) sheets doped with GaN and BN were produced in a horizontal CVD reactor using the floating catalyst method. The synthesis was performed at 1400 °C for 1 h with a fuel injection rate of 30ml/h. Tris(dimethylamido)gallium (III) and Tris(dimethylamino)borane were used as precursors for GaN and BN respectively along with n-hexane and methanol as a carbon source and ferrocene as the catalyst. Hydrogen and argon with a flow rate of 150 sccm and 1400 sccm were used as carrier gases. After synthesis the structure and morphology of the carbon nanotubes in the sheets were studied using SEM secondary imaging. Analysis of the purity and the intrinsic defects of the CNTs were analyzed using Raman spectroscopy. Electrical conductivity measurements were performed using Four Point Probe.
