A crystalline Boron (B)-and Nitrogen (N)-co-doped microwave-assisted reduced graphene oxide (BNMRGO) film was investigated as a potential transparent conducting electrode (TCE) material. X-ray diffraction results revealed the good crystallinity of the BNMRGO film, and the presence of a (0004) reflection plane indicated the formation of a few small domains of hexagonal boron nitride in the microwave assisted reduced graphene oxide (MRGO) sheets under the co-doping process. Raman and X-ray photoelectron spectroscopic results indicated a reduction of sp(3) carbon centers upon codoping. The I-D/I-G ratio decreased after co-doping from 0.89 to 0.24, indicating a low average defect density of similar to 1.01 x 10(10) cm(-2). Optoelectronic characterization of the BNMRGO film on a glass substrate revealed a high optical transparency of 82% at 550 nm and a low sheet resistance (R-sh) of 355 Omega/sq, which was lower than that observed from the MRGO sheets (R-sh = 719 Omega/sq). BNMRGO provided a ratio between the direct conductivity (sigma(dc)) to the optical conductivity (sigma(oc)), that is, the figure of merit of a TCE material, of 5.96. Overall, this work paves the way toward developing a manufacturable TCE. Published by AIP Publishing.
