Bandgap-Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton-Coupled Electron Transfer for Stable Thermoelectrics

A. Hawkey, X. Rodríguez-Martínez, S. Lindenthal, M. C. F. Jansen, R. Crispin and J. Zaumseil, Adv. Electron. Mater., 2025, 2400817 Networks of semiconducting single-walled carbon nanotubes (SWNTs) are a promising material for thermoelectric energy harvesting due to their mechanical flexibility, solution processability, high Seebeck coefficients and high electrical conductivities after chemical p- or n-doping. Here, …

Ion-Exchange Doping of Semiconducting Single-Walled Carbon Nanotubes

A. Hawkey, A. Dash, X. Rodríguez-Martínez, Z. Zhao, A. Champ, S. Lindenthal, M. Zharnikov, M. Kemerink and J. Zaumseil, Adv. Mater., 2024, 2404554 Semiconducting single-walled carbon nanotubes (SWCNTs) are a promising thermoelectric material with high power factors after chemical p– or n-doping. Understanding the impact of dopant counterions on charge transport and thermoelectric properties of …

Soluble alkali-metal carbon nanotube salts for n-type thermoelectric composites with improved stability

B. Dörling, X. Rodríguez-Martínez, I. Álvarez-Corzo, J. S. Reparaz and M. Campoy-Quiles, Appl. Phys. Lett., 2021, 118, 213901. We present a method to dissolve carbon nanotubes that simultaneously allows to prepare n-doped films. These films are composed of thinner bundles of longer tubes when compared to films prepared using surfactants and sonication. Their negative Seebeck …
