• W2320147275 abstract "We present a high-pressure optical and infrared spectroscopy study on the mechanical stability of single-walled carbon nanotubes (SWCNTs) filled with C60 and C70 fullerene molecules (C60- and C70-peapods), double-walled carbon nanotubes (DWCNTs) derived from the C60- and C70-peapods (DWCNTs/C60 and DWCNTs/C70), and iodine-filled SWCNTs (I-SWCNTs). High-resolution transmission electron microscopy, Raman, and optical spectroscopy were used to characterize all prepared samples. For the C60- and C70-peapods, we find an anomaly in the pressure-induced shifts of the optical transitions at the critical pressures Pc1 ≈ 6.5 and 7.0 GPa, respectively, compared to Pc1 ≈ 3 GPa in the case of empty SWCNTs. The shift of the anomaly to higher pressure signals the stabilization of the nanotubes by the C60 and C70 filling. The value of Pc1 is in good agreement with theoretical predictions of the pressure-induced deformation for highly filled peapods with similar average diameter. In comparison to SWCNTs, the pressure-induced red shifts of the optical transitions in DWCNTs/C60 are extremely small below ∼10 GPa, demonstrating the enhanced mechanical stability due to the inner tube. The anomaly at the critical pressure Pd ≈ 12 GPa in DWCNTs/C60 signals the onset of the pressure-induced deformation of the tubular cross sections or the collapse of the DWCNTs. For the DWCNTs/C70, the anomaly in the pressure-induced shift is lowered to Pd ≈ 9 GPa compared to 12 GPa in the case of DWCNTs/C60. This behavior signals that the stabilization of the outer tube by the inner tube in DWCNTs/C70 is lower compared to the DWCNTs/C60. Interestingly, the iodine filling shows a stabilization for the outer tubes up to 10 GPa in contrast with the previously published Raman results. For all samples, except I-SWCNTs, the low energy absorbance decreases rapidly with increasing pressure, suggesting the destruction of the SWCNT electronic band structure and hence an increasing carrier localization. In the I-SWCNTs the pressure-induced free carriers localization is partially compensated by the metallization of the iodine chains under pressure." @default.
