Description
  • Mody ve střední části spectra (IFM) jednostěnných (SWCNT) a dvojstěnných uhlíkových (DWCNT) byly analyzovány pomocí Ramanské spektroskopie a in-situ Ramanské spektroelektrochemie. Vnitřní a vnější tuby v DWCNT mají od sebe oddělené pásy v oblasti IFM. To potvrzuje závislost IFM na poloměru tub. Provedená analýza pásů vnitřních tub umožnila přesnější přiřazení těchto pásů signálům, které jsou vlastní pro uhlíkové nanotuby. Přestože se předpokládá, že vnitřní tuby v DWCNT jsou strukturně perfektní, byl diskutován vliv defektů na IFM. Dále byla detailně studována a diskutována závislost IFM na elektrochemickém dopování. Bylo ukázáno, že In situ spektroelektrochemie otevírá cestu k rozlišení pásů vnitřních a vnějších tub. (cs)
  • The intermediate frequency modes (IFM) of single-walled carbon nanotubes (SWCNTs) and double-walled carbon nanotubes (DWCNTs) were analyzed by Raman spectroscopy and in situ Raman spectroclectrochemistry. The inner and outer tubes of DWCNTs manifested themselves as distinct bands in the I FM region. This confirmed the diameter dependence of IFM frequencies. Furthermore, the analysis of inner tubes of DWCNTs allowed a more-precise assignment of the bands in the IFM region to features intrinsic for carbon nanotubes. Although the inner tubes in DWCNTs are assumed to be structurally perfect, the role of defects on IFM was discussed. The dependence of IFM on electrochemical charging was also studied. In situ spectroelectrochemical data provide a means to distinguish the bands of the outer and inner tubes.
