Covalent functionalization offers a versatile platform to engineer carbon nanotube properties for optoelectronics applications. We demonstrate by atomistic quantum dynamics simulation that covalent functionalization can renormalize the CNT band gap, split the degenerate CNT band edge states, and strongly influence charge carrier separation and recombination dynamics. Open-ring CNT functionalization (O-CNT) largely retains the π-conjugation, whereas ...

Gayduchenko I., Prudkoglyad V., Kuntsevich A., Physical Review B: Condensed Matter and Materials Physics 2024 Vol. 109 No. 16 Article L161401
Despite decades of intensive studies, some aspects of charge transport through carbon nanotubes (CNTs) remain poorly understood. Here, we explore the transport properties of field-effect devices based on metallic CNTs, where the density of states is supposed to be constant and a field effect is not anticipated. The observed current-voltage characteristics are qualitatively different from ...
