Abstract
This study focuses on the fabrication and characterization of flexible thermoelectric generators (TEGs) using nitrogen-doped single-walled carbon nanotubes (N-SWCNTs). N-SWCNT films were synthesized using Floating Catalyst Chemical Vapor Deposition (FC-CVD) with acetonitrile and pyridine as precursors and integrated into TEGs. The optimized TEG design enhances performance and simplifies electrical connections compared to conventional designs. Characterization techniques, including UV-Vis spectroscopy, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS), confirmed the diameter, nitrogen content, Seebeck coefficient, and resistivity of the N-SWCNTs. The results highlight the potential of N-SWCNT-based TEGs for flexible electronics applications.Description
