Curved aromatic corannulene as an efficient enhancer for n-type thermoelectric single-walled carbon nanotubes

Abstract

Enhancement of the thermoelectric properties of n-type single-walled carbon nanotubes, SWCNTs, is strongly desired for future thermopower source. We here report remarkable simultaneous enhancement of the thermoelectric properties by secondary...

Photoinduced electron doping of single-walled carbon nanotubes based on carboxamide photochemical reactions

“…S6 †). Because hydroxyl ions and DMBIc produced by UV irradiation are known as electron dopants, 47,48 our ndings suggest that DMBI-Ox can be used as a dopant for semiconductors by UV irradiation.…”

Molecular Doping Modulation and Applications of Structure‐Sorted Single‐Walled Carbon Nanotubes: A Review

“…It seems that stable n-doping for sorted SWCNTs is more difficult compared to pristine SWCNTs even by using the same type of dopants. [13,55,200] Yet, by applying passivation layers, it has been proven that the n-type s-SWCNTs can have the same capability as their p-type counterparts for obtaining a high power factor. [13]…”

Dopant-Inherent Mechanisms of Atmospheric Stability in Chemically N-Doped Semiconducting Carbon Nanotubes Revealed by Tracking Optical Absorption

“…By tracking the optical absorption corresponding to the first excitonic transition between the van Hove singularity ( S 11 ), the air sensitivity of n-doped semiconducting CNTs is selectively observed over time, even in films containing both semiconducting and metallic CNTs. Using a kinetic technique, the comparison study on the air stabilities of semiconducting CNTs for different n-type doping systems has also been conducted: CNTs doped with supramolecular salt-based dopants (i.e., crown ether complexes) ,− and that doped with superelectron donor (SED) reagents (i.e., 4-(2,3-dihydro-1,3-dimethyl-1 H -benzimidazol-2-yl)- N , N -dimethylbenzenamine ( N -DMBI)) . These doping systems are well-known for their excellent stabilities and characteristic advantages in various applications.…”
