microscopy, we measured the absorption
cross section of (6,5) carbon nanotubes at their second-order optical
transition. We obtained a value of 3.2 × 10–17 cm2/C atom with a precision of 15% and an accuracy below
20%. This constitutes the first metrological investigation of the
absorption cross section of chirality-identified nanotubes. Correlative
absorption–luminescence microscopies performed on long nanotubes
reveal a direct manifestation of exciton diffusion in the nanotube.
