Graphitic carbon, formed by laser-induced graphitization, can be applied as a thermoelectric element in thermoelectric power generation devices. Because conventional graphitic carbon exhibits p-type thermoelectric properties mainly due to the adsorption of atmospheric species, the fabrication of graphitic carbon exhibiting n-type thermoelectric properties is expected to contribute to enhancing the output voltage of these devices. In this study, we demonstrated the fabrication of graphitic carbon structures exhibiting n-type thermoelectric response by introducing nitrogen atoms that can act as electron donors into graphitic carbon structures through laser irradiation in the presence of aniline.
