Publikováno v: Japanese Journal of Applied Physics. 61:121004

Semiconducting single-walled carbon nanotubes (s-SWCNTs) are promising materials for thermoelectric generation (TEG) because of their large theoretical Seebeck coefficient (S). In this study, to discuss superiority of s-SWCNTs for TEG devices, thermo

Electron doping of single-walled carbon nanotubes using pyridine-boryl radicals

Autor: Tsuyohiko Fujigaya, Aleksandar Staylkov, Aoi Hamasuna, Taiki Ishii, Takuto Uchida, Naoki Tanaka, Ryohei Yamaguchi

Publikováno v: Chemical communications (Cambridge, England). 57(49)

Pyridine-boryl (py-boryl) radicals serve as efficient electron-doping reagents for single-walled carbon nanotubes (SWCNTs). The doping mechanism comprises electron transfer from the py-boryl radical to the SWCNT. The formation of a stable py-boryl ca
